When user A goes off-hook, this presence information will be reported on the Jabber client of user B. To enable easier dial-peer configuration with non-overlapping destination patterns for inbound and outbound calls, again we want to prefix all E.164 called party information with "*" when sent to the Cisco Unified Border Element terminating the SIP trunk. Table 2-36 Phone Localization Calling Party Transformation Patterns, Any US destination: +12125551234 > 912125551234, Any international destination: +4961007739764 > 90114961007739764, Call from local DN range: +14085554001 > 4001, Call from local non-DID range: 81405001 > 5001, Call from local DN range: +19725555001 > 5001, Call from local non-DID range: 81976001 > 6001, Call from local DN range: +19195551001 > 1001, Call from local non-DID range: 81912001 > 2001. Table 2-43 shows the required settings to be configured under System/LDAP/LDAP Directory. This setting allows you to define incoming calling and called party transformations per numbering type to be applied to incoming calls on gateways. Cisco Jabber can be deployed in either of two modes: This is the default mode. The focus of this chapter is the Deployment Overview section. Holds +E.164 route patterns required to provide PSTN access to national destinations in the US. 5. Service Discovery enables Jabber to establish configuration automatically. As discussed in the sizing section, a single subcluster can be deployed in order to support up to 15,000 users. To achieve this goal, custom LDAP filters can be used to define two groups of users: local and remote. 31 Lobby). Table 2-27 shows the configured PSTN route patterns. GDPR can advertise a +E.164 number, one Enterprise Significant Number (ESN), and up to five alpha-numeric URIs per directory number. MRGL Audio would need to be assigned to devices requiring access to audio conferencing media resources only, while MRGL Video would allow access to video conferencing resources. Germany: national call (00-national significant number). For example, if a site in Germany has four-digit extensions starting with 9 (such as +E.164 range +49 6100 773 9XXX), then the abbreviated four-digit intra-site dialing defined for that site through a 9XXX dialing normalization translation pattern creates an overlap with the US emergency dialing 911 if a user from that German site logs into a phone in the US. By leveraging Survivable Remote Site Telephony (SRST) on a Cisco IOS router in each branch location, basic IP telephony services can be maintained for the desk phones if connectivity to the centralized call processing platform is lost. Cisco Unified CM is the central call control component in any Cisco collaboration deployment. The recommended format for the ESN schema is an access code chosen so that no overlap between ESN dialing and other dialing habits is created, followed by a site code and the intra-site extension. Route groups combine trunks with common characteristics. 4 Chapter 1: Cisco Unified Communications Manager Architecture CUCM Overview Cisco Unied Communications (UC) is an IP-based communications system integrating voice, video, data, and mobility products and applications. In this design we will not use the default MRG because it makes troubleshooting of media resource selection more complicated. Call from +E.164 DN in the SJC DID range; display follows abbreviated intra-site dialing habit. Make sure that UDS-based service discovery for this user does not resolve to the local Unified CM cluster. Because Germany and France use the same emergency dialing habit, the emergency routing can be simplified by combining both emergency partitions DEEmergency and FREmergency into a single partition 112Emergency and by using that partition instead in the CSS definitions. Calls from phones registered with the central Unified CM will fail, though, because from the central Unified CMs perspective the called device is unregistered and thus unreachable. The ILS cluster discovery service enables UDS-based service discovery for Jabber clients in multi-cluster environments. Same for all devices and device pools, although not really required for a PSTN trunk. For each defined LRG name, the route group selected for that LRG name defines which devices will be considered for a call of the selected type (defined by the route pattern matching on the called number and pointing to a route list referring to specific LRGs). Locally configured users are always authenticated against the local database. If the primary CTI Manager Service fails but the primary CCM Service is still running (assuming you have 1:1 redundancy with a distribution of 100%/0% on the primary/backup Unified CM subscribers), then all the devices will stay registered to the CCM Service running on the primary Unified CM subscriber, and the CTI Manager running on the backup Unified CM subscriber will become active and will monitor and control the CTI devices even though they are registered to a CCM service running on a different node (the primary Unified CM subscriber in this case). I was thinking that Cisco is the cloud provider for UCCE/UC and the partners are there to help with the design/implementation. So PSTN resources of one site are selected via the Standard Local Route Group configuration. 5. For example, a CUCM, Cisco Unified CMBE, or CUCM Express in San Jose can process call control for a device physically located in Chicago. Following the maxim to avoid and eliminate redundancies in the dial plan as much as possible, the concept of Local Route Groups (LRGs) is used to define the egress gateway selection. Each application running on an Apple iOS platform registers with APNs to be able to receive notifications via APNs and receives a device and application specific device token. The handling and processing of voice and video calls is a critical function provided by enterprise communications systems. For the example cluster hosting the sites RTP, RCD, and SJC, the patterns shown in Table 2-68 need to be configured as GDPR advertised patterns. John Kull Wed, Sep 28 2022 networking 3. After configuring the SIP trunks and route groups, you can come back and set the LRG mapping. The Cisco UC strategy encompasses voice, video, and data traffic within a single network infrastructure. To allow for a very simple provisioning of Unified CM presence without further differentiation of presence access, a single CSS needs to be provisioned that allows access to all possible on-net destinations. Create a CTI service for each Unified CM running the CTI Manager service. Access to the enterprise collaboration network and to Unified CM from the Internet to enable remote access and business-to-business secure video communications, is also available through various collaboration edge solutions such as VPN and Cisco Expressway. In a multi-cluster deployment, interconnect all the individual Unified CM clusters through SIP trunks. Ping Interval for Out-of-service Trunks (seconds). Note The numbering plan in Germany is variable length and this pattern needs to cover this. Table 2-70 summarizes the trunks, route groups, route lists, and SIP route patterns that need to be provisioned to enable full intercluster GDPR routing between two Unified CM clusters. For users connected to the internal enterprise network (not using Cisco Collaboration Edge), directory search Contact Sources can be provided through UDS or through LDAP. If selecting different outbound PSTN resources based on call type is not required for a given set of devices, and only a single PSTN resource is needed for all call types, then it is sufficient to define only an actual route group for the Standard Local Route Group on the respective device pool and leave all other LRGs in that device pool set to
. Cloud-Connected UC is a suite of Webex cloud services with a single global view to manage on-premises UC and Unified CM cloud services. In this design, in addition to alpha URI dialing, the numeric dialing habits shown in Table 2-11 are supported. See the section on Phone NTP References. PSTN E.164 numbers for these services have to be reserved from the DID ranges assigned by the PSTN providers. Cisco is a leading innovator of collaboration technologies and solutions. A digit sequence uniquely identifying the respective entity within the site. . 4 Chapter 1: Cisco Unified Communications Manager Architecture CUCM Overview Cisco Unied Communications (UC) is an IP-based communications system integrating voice, video, data, and mobility products and applications. Prefix ST_ to avoid name collisions with other devices stored in the same table internally. Make sure to set the interval small enough to pick up corporate directory changes in a reasonable time, but keep in mind that executing the LDAP synchronization creates significant load on the Unified CM publisher. Password-based authorization is selected. Deploy all nodes using Cisco Prime Collaboration Deployment. The actual site-specific dialing normalization is irrelevant here. Synchronization of Unified CM with a corporate LDAP directory allows the administrator to provision users easily by mapping Unified CM data fields to directory attributes. Unified CM provides foundation services including call control, endpoint registration, endpoint configuration, call admission control, codec negotiation, trunk protocol translation, and CTI. Table 2-24 Inbound CSS for Trunks to Other Unified CM Clusters. For a complete discussion of system sizing, capacity planning, and deployment considerations related to sizing, refer to the chapter on Collaboration Solution Sizing Guidance. Set the Enterprise parameter OAuth with Refresh Login Flow to Enabled. To create an ILS network of multiple Unified CM clusters, perform the following tasks: The cluster IDs defined in the Unified CM cluster enterprise parameters have to be unique. Hence, initially you need to configure the device pool and leave the LRG mapping set to . Endpoints layer: The endpoints layer brings applications to the user, whether the end device is a Cisco IP Phone, a PC using a software-based phone, or a communications client or video terminal. To connect to services, Cisco Jabber requires the following information: In full UC or IM-only modes, the source of authentication is the IM and Presence service. In addition, proper WLAN infrastructure design requires understanding and deploying QoS on the wireless network to ensure end-to-end voice and video quality on the entire network. The Unified CM Group provisioned on the device pool determines the Unified CM call processing subscribers to which devices associated with the given device pool will try to register. All +E.164 patterns are provisioned as urgent patterns. The user's availability status indicates whether or not the user is actively using a particular communications device such as a phone. For this SIP trunk, configure the destination IP addresses of all IM and Presence nodes. Make sure to use the same synchronization interval on all clusters for consistency. Table 2-14 Summary of Dialing Normalization Translation Patterns, Abbreviated inter-site dialing to site SJC, Abbreviated inter-site dialing to site RCD, Abbreviated inter-site dialing to site RTP, Abbreviated intra-site dialing in site SJC to DID in SJC, Abbreviated intra-site dialing in site SJC to non-DID in SJC, Abbreviated intra-site dialing in site RCD to DID in RCD, Abbreviated intra-site dialing in site RCD to non-DID in RCD, Abbreviated intra-site dialing in site RTP to DID in RTP, Abbreviated intra-site dialing in site RTP to non-DID in RTP, US specific habitual PSTN dialing to national destinations in the US. 4. MRGL with access to audio conferencing media resources in MRG Audio. Hence, calling and called party transformations required to adapt to service provider requirements cannot be done on the route pattern or route list level. In addition to enabling UDS-based service discovery for Jabber clients, provision DNS SRV records for all Unified CM publisher and TFTP subscriber nodes, defining these as service locations for _cisco-uds. Table 2-9 indicates an ESN range for the DID and non-DID numbers for each site in our example. For the definition of the CSS, see the section on Special CSSs. Collaborate anywhere, anytime. Of special consideration are calls originating from phones with non-DIDs. From the Service drop-down list, choose Cisco XCP Router (Active). To enable UDS-based service discovery, the UDS process on each Unified CM cluster tries to establish connectivity with the UDS processes running on remote Unified CM clusters to learn about the remote clusters' UDS nodes. All rights reserved. When routing numeric SIP URIs, Unified CM considers SIP URIs with the right-hand side (host portion) of the URI matching the configured Cluster Fully Qualified Domain Name (CFQDN) as destinations to be routed according to the configured local numeric dial plan. This password is shared among all Unified CM clusters participating in the ILS network. The remainder of the name identifies the trunk's purpose. When defining the partitions and CSSs provisioned to build an enterprise dial plan, one goal is to avoid replication of duplicate configuration as much as possible. MRGLs and MRGs are constructs that hold related groups of media resources together for allocation purposes. Device pools define sets of common characteristics for devices. As mentioned earlier, SIP does not have the concept of "typed" numbers. To enable authentication, a single authentication agreement is defined for the entire cluster. If video conferencing capabilities were the exception, we could decide to use only one device pool per site with MRGL set to Audio and then on the few video-enabled devices set the MRGL to Video in the device configuration. Table 2-48 Example Date/Time Group Definitions. For dialing domains other than the US, other country specific dialing normalization translation patterns must be defined if the installation has to support those country specific dialing habits. The calling party transformation patterns in Table 2-33 perform the required transformations that make sure any calling party number, whether in the form of a +E.164 number or an enterprise specific number not matching the trunks DN range, is forced to a main number (19195551888). Cisco UCM Cloud is part of Cisco's cloud calling portfolio and is powered by Cisco's Unified Communications Manager collaboration (CUCM) technology, and is hosted in Cisco's Webex data centers across the globe. Cisco UCM Cloud, Cisco Unified IM&P, and Unity Connectionare included as part of this transition scenario. PSTN access is achieved through PSTN route patterns. Regular SIP intercluster trunks are used for GDPR routing. During this onboarding process a machine account is created for the specific cluster in the Cisco Collaboration Cloud, and an OAuth refresh token is issued for the cluster. The ILS cluster discovery service allows Unified CM to learn about remote clusters without the need for an administrator to manually configure connections between each cluster. MeetingPlace Express is the successor of the Cisco Conference Connection server. As discussed in the section on Unified CM and IM and Presence Service Clustering, the IM and Presence nodes are considered part of the larger Unified CM and IM and Presence Service cluster. Streamlined deployment empowers you to expand access and accelerate the application experience across all branches of your organization. The leading RL makes sure to avoid naming collisions with trunks. The Contact Source or directory can be configured through the jabber-config.xml file or through the directory UC service which takes precedence. Collaboration Architect, Shervin Shaffie, will walk you through Cisco Cloud Calling. The leading "*" on all called party numbers sent from Unified CM to the gateway allows the use of "destination-pattern *" on the POTS dial peers on the gateway. As long as the emergency dialing habit is more specific, then creating the emergency calling route pattern as urgent pattern makes sure that no delay is experienced when placing an emergency call. With the above configuration, this section describes how a call would be routed if +14085554001 is dialed on an endpoint with class of service "international" registered to the EMEA cluster in the above example. Are post-sales documents that describe optional designs that can be deployed as alternatives to the Preferred Architectures described in the PA overview guides and CVDs. The last member, Standard Local Route Group, allows for fallback to PSTN resources not specific to a call type. To deploy the Unified CM and IM and Presence Service cluster, perform the following tasks: 1. The order of the topics in the Deployment Overview section follows the recommended configuration order. Determines the time interval for call detail record (CDR) file updates, URLs used by endpoints for various purposes, Make sure these URLs refer to the FQDN of the Unified CM publisher node. If you want SIP phones to get their date and time from NTP servers, then in the date/time group you prioritize the phone NTP references, starting with the first server that you want the phone to contact. If you want to do so, you can configure phone Network Time Protocol (NTP) references in Cisco Unified Communications Manager Administration to ensure that a phone running SIP gets its date and time from the NTP server. This functionality is handled by some type of call processing entity or agent. It is important to set route groups for all defined LRG names to avoid call failures due to route lists not containing any valid PSTN resources. Signaling is also referred to as call control and call setup/call teardown. Example 2-1 shows an example of DNS SRV records defining a number of Unified CM nodes as _cisco-uds service locations. The service offers the same familiar CUCM features and user experience providing an ideal migration path to the cloud for enterprise . The Unified CM architecture enables a group of server nodes to work together as a single call processing entity. Cisco UCM Cloud is part of Cisco's cloud calling portfolio and is powered by Cisco's Unified Communications Manager collaboration (CUCM) technology, and is hosted in Cisco's Webex data centers across the globe. MRGL defining the media resources available for a group of devices. Management and administration are centralized. European data centres and Asia-Pacific solutions are also coming soon. The 10 most powerful companies in enterprise networking 2022. Indicates that this LDAP synchronization agreement synchronizes local users. Table 2-40 shows two custom LDAP filters, assuming that our deployment has users in the US and Europe and that only the US users are considered as local users. It provides this capability while maintaining high availability, QoS, and security. Table 2-3 Unified CM Node Service Activation, Cisco Certificate Authority Proxy Function. Call processing: Call processing refers to the complete process of originating, routing, and terminating calls, including any billing and statistical collection processes. Different number formats might be used, depending on the provider, and this will require use of different transformations on the gateway or on Unified CM. 2022 Cisco and/or its affiliates. This parameter enables or disables the logging of call detail records (CDRs) for calls that never connected or that lasted less than 1 second. On ISDN trunks, some providers always allow called and calling party numbers independent of called destination to be sent using the same ISDN plan and type indication. If the CTI limit is reached, deploy another pair of Unified CM call processing nodes running the CTI Manager service. To achieve this, navigate to System/Server in the Cisco Unified CM administration GUI and verify that all servers show up in the first column as FQDNs. Remember that for SIP trunks the setting for number type Unknown Number is relevant on the device pool level. In addition to providing reliable FQDN-to-IP-address (and reverse) resolution, DNS also is required for the automatic service discovery process used by Jabber clients. This also allows for abbreviated four-digit intra-site dialing to non-DIDs and DIDs. Table 2-20 Class of Service International for Users in site FRA in Germany (DE), DN Directory URI URI ESN onNetRemote FRAIntra DEtoE164 DEPSTNNational PSTNInternational B2B_URI DEEmergency. The jabber-config.xml file is also used to enable URI dialing for Jabber clients. Enables LDAP authentication for the Unified CM cluster. Even if no format transformation is required for calling party information sent on a SIP trunk, some filtering still needs to be applied to the calling party information to make sure that only valid numbers are sent to the provider. If a non-DID is provisioned, then the partition is ESN. Learn more about how Cisco is using Inclusive Language. The recommendation is to configure a jabber-config.xml file that is uploaded onto the Unified CM TFTP server. Examples for such trunks include trunks to other Unified CM clusters and applications. Make sure to provision redundant servers, if possible. Cisco Unified Contact Center promotes efficient and effective customer communications across large networks by enabling organizations to draw from a broader range of resources to service customers. If calling and called parties are received in E.164 format, then the easiest way to transform to +E.164 is to simply configure a prefix "+" on the SIP trunk in Unified CM or on the trunk's device pool. When you create the device pool, the required route group does not exist yet. Table 2-15 shows the required dialing normalization for Germany (DE) and Italy (IT) as examples. Hence, us.route is matched against the configured SIP route patterns on the EMEA cluster, again using the calling device's CSS XXXInternational. This chapter examines the various types of call processing applications and platforms that facilitate voice and video call routing. For the same reasons, redundant devices and network links that provide quick convergence after network failures or topology changes are also important to ensure a highly available infrastructure. It enables more effective, secure communications and can transform the way in which we communicate. If more than three Unified CM clusters are required, then adding Unified CM Session Management Edition (SME) is recommended to simplify the topology to a hub-and-spoke topology with SME as the hub and all other Unified CM clusters as spokes or leaf clusters. This parameter determines whether call management records (CMR), also called diagnostic records, are generated. According to (Cisco 2019) almost 80% of companies are considering making the transition of their communication platforms to the cloud, in the future this number is only going to go up as companies See Table 2-32 . in partition PSTNInternational (see Table 2-27 ), \+!# in partition PSTNInternational (see Table 2-27 ). Cisco Unified Communications Manager Group. A dedicated LDAP synchronization agreement is also required to synchronize the remote users who do not use UC services on the local Unified CM cluster. OAuth grant flow authentication makes sure that a Jabber client receiving an incoming call APN can be brought to the foreground and re-authenticate quickly enough for the user to answer the incoming call in a timely manner. Unified CM and IM and Presence systems also handle high availability at the application level. Cisco is uniquely positioned as a leading vendor in networking, data center, collaboration and . Table 2-61 Route Group for Intercluster Trunk to Other Unified CM Cluster. The default digit stripping behavior of Cisco IOS will then automatically strip the leading "*". CSSs for classes of services for users in other sites are created equivalent to the above CSSs, with the only difference being a different partition used with the site-specific dialing normalization patterns. The benefits of this approach include the following: Unique addresses are also required for endpoints without an associated DID (for example, lobby phones) and enterprise services (for example, call pickup, call park, and so forth). This CSS defines the calling party transformations applied to calling party information sent in the direction of the affected device. It is important to make sure that certificates issued by the CA have the required key usage and extended key usage. Cisco Survivable Remote Site Telephony (SRST) is used to implement backup services for remotes sites when the corporate WAN reliability does not match the voice services availability requirements. LDAP synchronization is executed periodically. In scenarios where Cisco Unity Connection needs to serve multiple countries, then implementing the country specific dialing normalization as defined in partition UStoE164 in the above example is not an option. For devices associated with users, after provisioning the device in the End User Configuration of the respective user in the Device Information section in Unified CM Administration, make sure that the device is associated with the user. Extension Mobility Cross Cluster (EMCC) provides the ability to perform Extension Mobility logins between clusters within an enterprise. Some services have assigned PSTN numbers. The classes of service chosen for this design are only examples. With the Service Discovery method, the client automatically locates and connects to services. GDPR allows you to quickly configure the global dial plan across the ILS network without the need to configure each dial plan component on each cluster separately. Determine the number of required call processing subscriber pairs based on the target number of users and devices. Cisco's leadership in Cloud security means that one can be assured that customer's receive best-in-class security whether its at the . Also, this server-to-server communication is one of the reasons why TLS Web Client Authentication has to be in the X.509 extended key usage when issuing Tomcat certificates on an external CA. Note Do Not Wait For Interdigit Timeout On Subsequent Hops is not set. If this configuration applies to your deployment, and login speed is unacceptable, it is possible to set the authentication configuration to use a Global Catalog Server. Follow the steps outlined in the section on Server Certificate Generation and Management in the Security chapter. The system architecture lays the foundation upon which all components of the Unified Communications and Collaboration System are deployed. Also, the DNS resolver configured in Unified CM IM and Presence Service and in Unified CM call processing nodes must allow resolution of externally routable addresses. What is Webex Calling? Table 2-52 Device Pool Settings for PSTN Gateways in Site RTP. ESN range of RCD DIDs. For a detailed explanation of voice translation rules, see the document on Number Translation using Voice Translation Profiles, available at, https://www.cisco.com/c/en/us/support/docs/voice/call-routing-dial-plans/64020-number-voice-translation-profiles.html. Tip On dialing normalization translation patterns, set the option Use Originator's Calling Search Space so that the CSS used for the secondary lookup is identical to the CSS used for the primary lookup. 24.08.2016 15:01:47. This allows definition of dialing normalization translation patterns that can be reused in multiple context, because after applying the dialing normalization, the secondary lookup of the normalized digit string is executed, not based on a single fixed CSS, but based on the CSS in effect when the translation pattern was engaged. ESN range of SJC non-DIDs. The mid-market or Small to medium deployments with up to 1,000 users is no longer differentiated from the Enterprise market segment in the Preferred Architectures. Applications layer: Applications are independent from call-control functions and the physical voice-processing infrastructure. Table 2-29 shows the difference between fixed and variable length numbering plans. When deploying Cisco desk phones in branch locations separated from a centralized call processing platform by a low-speed or unreliable WAN link, it is important to consider local call processing redundancy. Rule 1 in Example 2-3 replaces a leading "*" with a leading "+" while rule 2 just prefixes a "+" to all numbers. The system architecture lays the foundation upon which all components of the Unified Communications and Collaboration System are deployed. Make sure to consider the TFTP servers also. The services are configured through UC services. To make sure that the user's directory URI synchronized from LDAP propagates to the directory number, select the Primary Extension in the Directory Number Associations section in the End User Configuration of the respective user in Unified CM Administration. Figure 2-1 Enterprise Collaboration Deployments: On-Premises, Cloud, and Hybrid. If a non-DID is provisioned, then the directory number is set to the ESN (for example, 81405001). As mentioned before, a CSS is a list of partitions that defines which partitions, and thus patterns, a calling entity using the CSS can access. Setting the synchronization interval to a reasonably small interval makes sure that changes are picked up by remote clusters after a short period of time. Only features and functions for on-premises calling, messaging, and presence were evaluated with the UCM Cloud solution environment. Full +E.164 directory number matching the phone number of the user this DN is provisioned for. In this case, if a user roams between countries with different emergency dialing habits, then the device this user is using inherits the emergency dialing habits specific to the visiting user. One or two Unified CM call processing nodes can actively handle Extension Mobility requests. I am currently running UCCE/CUCM and UCNX. On each endpoint, at least the first line needs to be provisioned. Think of it as if a GDPR route strings tells us "where" a learned URI or numeric pattern is located, and we need route patterns matching on these route strings to tell how to get to this destination. Figure 2-1 illustrates, in a generalized way, how collaboration applications and services can be delivered solely on-premises, solely in the cloud, or in combination as a set of hybrid service deployments. Keep in mind that this combination of dialing habits between different countries might create overlaps between the visited sites' emergency dialing and the visiting user's regular dialing habits. 31 Lobby). In this design we do not need this differentiation and simply configure GDPR to learn all remote numeric patterns in a single partition, onNetRemote (see Table 2-12 ). Meaningful name; in this case, for the route group holding only the intercluster trunk to the EMEA Unified CM cluster. Simplifies administration. If both types of identity exist, then based on the capabilities of the called endpoint, the cluster terminating the call can decide which piece of the identity information can be displayed on the final called party. UC represents a communications paradigm shift like that of the invention of the telegraph. For endpoints with DID addresses, directory numbers are provisioned as full +E.164 numbers, where +E.164 represents a leading "+" followed by the full global E.164 phone number. UCM Cloud provides a smooth migration from on-premises deployments to the enterprise private cloud. Applications, including those listed here, are integrated through IP, which allows the applications to reside anywhere within the network: Voice mail, integrated messaging, and unified messaging applications are provided through Cisco Unity, Cisco Unity Express, or Cisco Unity Connections products. MRG Software added to provide access to MoH and annunciator. In this document we use 8 as the access-code for abbreviated inter-site dialing, and thus all ESNs start with 8 and use a three-digit site code and a four-digit extension. Figure 2-5 shows the overall architecture of the integration with APNs. For example: SJCPhLocalize. The key difference is that in that FGT the Home Cluster and Enable User for Unified CM IM and Presence options are not checked. Configuring these transformations on the device pool enables sharing the same settings with multiple gateways in the same site sharing the same called party transformation requirements. Cisco DNA for Routing gives you full control over your SD-WAN architecture. Table 2-23 shows the (trivial) CSS "DN" to be used as the incoming CSS on PSTN trunks. The interface between each Cisco IM and Presence cluster is two-fold: an AXL/SOAP interface and a signaling protocol interface (SIP or XMPP). All of the partitions Table 2-12 except the Directory URI partition must be created. Call from US; display follows PSTN dialing habit. It combines multiple security functions into one solution, so you can extend protection to devices, remote users and distributed locations anywhere. Table 2-16 lists the classes of service considered in this design. MRGs are used to group together media resources of similar characteristics, and MRGLs define a set of MRGs to be considered when selecting a required media resource for a session. Characteristics defined on the device pool include the settings shown in Table 2-50 . When LDAP synchronization is enabled, the local Unified CM database is still used, and additional local end-user accounts can be created. Contact centers of various sizes can be built with Cisco Unified Contact Center and Cisco Unified Contact Center Express. An ESN is the abbreviated inter-site dialing equivalent of a directory number. Table 2-67 shows the settings to apply when activating ILS on the remaining Unified CM clusters. Take users from their smartphone to their business devices in their office, home, or meeting room, with easy transitions and full business calling features. 2. G.722 disabled on recording-enabled devices to avoid problems with G.722 not being supported by the recorder. Cisco Unified CM provides call processing services for small to very large single-site deployments, multi-site centralized call processing deployments, and/or multi-site distributed call processing deployments. Irrelevant as long as only one route group member exists. This makes sense in scenarios where centralized PSTN resources are provisioned for normal PSTN calls, but emergency calls should still use dedicated small gateways local to the site to allow for local emergency call routing to the correct Public Safety Answering Point (PSAP). Video Cisco Smart Net . Both prefixes and calling and called party transformations can be defined either on the trunk level or on the device pool level. Holds all patterns of remote on-net destinations. This done by changing the role from Standalone Cluster to Hub Cluster in the ILS Configuration menu in Unified CM Administration. Strip digits and prefix to transform from ESN to PSTN failover number. Figure 2-8 Example Dialing Normalization Translation Pattern. Management of end-user accounts is then accomplished through the interface of the LDAP directory and Unified CM Administration. Table 2-69 summarizes the settings for the GDPR partitions. As shown previously, this is easily achieved by adding the partition with the emergency calling route patterns to all CSSs. Cisco Collaboration System 12.x Solution Reference Network Designs (SRND), View with Adobe Reader on a variety of devices, View in various apps on iPhone, iPad, Android, Sony Reader, or Windows Phone, View on Kindle device or Kindle app on multiple devices. Instead of adding the USEmergency to all CSSs, create a dedicated USEmergency CSS and assign that CSS as the device CSS on all devices in the US. Distinguished name of an AD account with read access rights to all user objects in the desired user search base. For sites in other dialing domains (countries), the same CSS and partition schema as shown above can be used, with the only difference being that the dialing normalization partition for the specific dialing domain and the partition with the country specific route to national PSTN destinations would be used instead of the US partitions used above. Unified CM is the central point of administration and provisioning. The presence user profile helps determine the scale and performance of an intercluster presence deployment and the number of users that can be supported. Rule 1 matches on any number (/^\(.+\)$/) with type international and simply prefixes +1 (/+\1/) while forcing plan and type to unknown because both are irrelevant when forwarded on the SIP trunk to Unified CM. For the SIP trunk to the IM and Presence nodes, configure a SIP trunk between Unified CM and IM and Presence. For service activation recommendations, see Table 2-3 . In these partitions the only (potential) match is on a +E.164 directory number \+14085554001 (marked urgent) in partition DN. From the Server drop-down list, choose the IM and Presence Service Publisher node. Because only the line CSS is used to define both class of service and the set of dialing habits available to a given caller, a CSS needs to be provisioned per site and class of service. If only one country (dialing domain) such as the US needs to be supported, then this CSS can be left as . UC removes the geographic barriers of effective communications through the use of voice, video, and data integration. While the ESN ranges in Table 2-9 leave room in the ESN plan for site-specific numbers, there is also a requirement to assign number ranges for non-site-specific services such as, for example, scheduled conferences. All rights reserved. The documentation set for this product strives to use bias-free language. In Italy the second zero has to be considered part of the NSN and hence has to be kept in the resulting +E.164 digit string, while a second zero in Germany would need to be removed because geographic numbers in Germany do not start with a zero. The remainder of the name identifies the location of the gateway and allows numbers for multiple gateways. The information advertised and learned through GDPR enables deterministic intercluster routing for these dialing habits: GDPR uses Intercluster Lookup Service (ILS) as the transport medium, therefore setting up ILS between all Unified CM clusters is required for multi-cluster deployments. Holds SIP route patterns required for business-to-business (B2B) URI dialing through the Internet. These transformations would be shared among all gateways. Remote clusters trying to reach any of the destinations advertised by this cluster will establish the route to this destination by matching the learned SIP route string against SIP route patterns provisioned on the remote cluster. To achieve the display format depicted in Table 2-35 , calling party transformation patterns need to be provisioned in adequate partitions, and calling party transformation CSSs based on these partitions have to be configured on the phones, to enable the transformations. The key here is that the inbound CSS provides access to local +E.164 destinations only. In that case we need to be able to differentiate between users who actually use UC services of the local cluster and users who are synchronized only to reflect the complete corporate LDAP directory on Unified CM. A two-node subcluster allows for users associated with one server of the subcluster to use the other server in the subcluster automatically if a failover event occurs. Describe the characteristics of the CUCM database and how it provides redundancy. Add or remove other access control groups as needed, but keep in mind that without Standard CCM End Users, the users will not be able to log into the self-service portal. The Cisco IOS translation shown in Example 2-4 assumes that we received called party information as type national and that the number in this case has only 10 digits. For example, if a user from Germany logs into a phone in the US, then the line CSS as defined on the German user's extension mobility profile gets assigned to the visited phone in the US, so that on this phone emergency calls now need to be placed using the German emergency calling dialing 112, and the US emergency call dialing habit 911 is not supported any longer. Cisco CallManager Administration groups SIP trunk security-related settings for example, device security mode, digest authentication, and incoming/outgoing transport type settings so you can apply all configured settings to a SIP trunk when you choose the profile in the SIP Trunk Configuration window. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Combined with Cisco Webex Calling and services from Cisco certified partners, the UCM cloud provides today's business leaders with a flexible and advanced solution to their digital transformation needs. Table 2-15 Dialing Normalization for Germany and Italy. Cisco ER identifies the caller location and maps all calls from that physical location to an emergency line identification number (ELIN) through the use of standard automatic number identification (ANI)/caller identification (CLID). Port to access global catalog (recommended). In contrast to the SIP trunk to a PSTN ISDN gateway, inbound calls from other Unified CM clusters in addition to +E.164 numbers also need access to ESNs and URIs. Holds all +E.164 directory numbers and other local on-net +E.164 destinations (for example, pilot numbers reachable from the PSTN). A structured, well-designed dial plan is essential to successful deployment of any call control system. The transformation from the called +E.164 destination to the digit string to be sent to the PSTN can be achieved on Unified CM, and on the gateway the ISDN plan and type can be enforced easily using Cisco IOS voice translation rules as shown in Example 2-2. Cisco Unified CM groups allow you to define groups of Unified CM instances in the cluster that determine which Unified CM instances should be used by devices to register to the Unified CM cluster. 6. Deploy one Cisco Integrated Services Router (ISR) for each remote sites that you want to enable for SRST. Table 2-45 shows an example of LDAP authentication settings. In multi-cluster deployments, use Global Dial Plan Replication (GDPR) to replicate dial plan information between clusters. The LDAP synchronization agreement in Table 2-43 ties together the FGT and custom LDAP filter defined before. To provide this information to the client, we recommend using the Service Discovery method over the Manual Connection method. From this perspective, my questions would be: 1. Cisco Collaboration Preferred Architectures. For more details, refer to the latest version of the following documents: https://www.cisco.com/c/en/us/support/unified-communications/jabber-windows/products-installation-guides-list.html. See Table 2-2 for details. Note Some of the service parameters listed are advanced service parameters. UCM Cloud-Customer Connected. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. The Cisco Unified CM IM and Presence Service provides on-premises instant messaging and presence. The chapter describes the call processing architecture, including platform options, clustering capabilities, and high availability considerations for call processing. Deploying this capability helps ensure more effective compliance with legal or regulatory obligations, thereby reducing the life and liability risks related to emergency calls. Both forward (from DNS name to IP address) and reverse (from IP address to DNS name) lookups have to be configured in the enterprise DNS. CUCM uses SIP or SCCP to communicate with Cisco IP Phones for call setup and teardown and for supplementary service tasks. Internally route lists are treated as devices, and the names of route lists cannot be identical to names of SIP trunks, for example. In addition to endpoints with associated DIDs for which +E.164 addresses can be used, a number of additional destinations exist for which no DIDs exist: In this document we refer to these types of destinations as non-DIDs. With SRST, if the WAN fails, phone calls can still be made within the remote site or out to the PSTN. To prevent this validation from failing, the Tomcat certificates of the Unified CM publisher and call processing subscriber nodes must be signed by a trusted CA. With this information, all IM and Presence nodes and call processing nodes of the cluster can then create connections to the Push REST service to issue notification requests targeted for specific Jabber clients (step 1). US specific habitual PSTN dialing to national destinations in the US. In the design phase, choose the access code so that there is no overlap with any other enterprise dialing habit (see below). The signaling protocol interface (SIP or XMPP) is a full mesh encompassing all servers within the deployment. Make sure that the SIP route string for each cluster is unique to allow for deterministic routing based on these route strings. This allows the affected phones to still place and received calls to and from phones in the same site and the PSTN. Unified CM groups are needed to distribute registrations equally among Unified CM call processing subscriber pairs (see the section on Cisco Unified CM Group Configuration). The status information includes the user's communications device availability. Messaging - voicemail and integrated messaging. Using inbound Cisco IOS voice translation rules is required only if different number types are sent by the provider. What is UCM Cloud? Note Route groups can be configured only after the SIP trunks have been created, and these can be added only after the respective device pool have been configured. For endpoints without a DID (endpoints with an ESN as directory number), the only meaningful rerouting for unregistered endpoints is to forward incoming calls to voicemail. The recommended way to achieve this is to select Device Association and search for devices where the directory number matches the phone number of the user. Defines date and time format and phone NTP references. Other service parameters of the Cisco CallManager service must be set explicitly as shown in Table 2-6 for each Unified CM call processing node. For best redundancy and load balancing, we recommend provisioning DNS SRV records with equal priority and weight for the Unified CM publisher and TFTP nodes. Also, we need to provision the transformation required to force the calling party number from +E.164 to whatever needs to be sent to the service provider. When Cisco IM and Presence is deployed in an intercluster environment, a presence user profile should be determined. For phones this CSS has no equivalent on the phone configuration page and does not have any effect when configured on a device pool used for phones. This chapter covers both intercluster and provider trunks, which provide the ability to route calls over IP and to leverage various Unified Communications and Collaboration features and functions. Inbound call number information treatment on PSTN SIP trunks is generally simpler than the number handling in the ISDN case described before. Route patterns configured to refer to a route list that makes use of LRGs will resolve to the actual route group configured as the LRG in the calling party's device pool. The recommended contact source for on-premises deployments is CDI. Describe how to calculate, verify, and add license units to CUCM. Refers to the custom LDAP filter described in the section on LDAP Custom Filter. This transformation makes sure that called party numbers are transformed from +E.164 to the format that can be sent as plan unknown and type unknown. Again we also need to create a CSS (for example, GWNoPlus) that addresses only partition GWNoPlus, and then apply this called party transformation pattern as Called Party Transformation CSS on either the gateway or the gateway's device pool. The intercluster peer is configured as the IP address of the remote Unified CM cluster IM and Presence publisher node. This is required for Push notifications via APNs. It uses standards-based XMPP and also supports SIP for interoperability with SIP IM providers. The call on the EMEA cluster is extended to SIP trunk ST_UCM_EMEA, dereferencing the route list RL_UCM_EMEA the matched SIP route pattern us.route points to and route group RG_UCM_EMEA (see Table 2-70 ). Additional information about our encryption architecture is . Sometimes when trying to decide between two UCaaS platforms, it is important to keep size in mind. The video LRGs are provisioned for video-enabled ISDN gateways and treat them as separate resources. High availability is recommended, and therefore in this design each subcluster consists of two nodes. This settings is recommended on all SIP trunks. If further classes of services are required, then these can be defined equivalently. Create one named Date/Time Group for each of the time zones in which you will deploy endpoints, as illustrated in Table 2-48 . Create a Voicemail service for each Unity Connection node. Table 2-57 SIP Trunk Security Profile for Intercluster Trunks. To configure SRST, you must perform the configuration on both Unified CM and the SRST router. Table 2-1 New or Changed Information Since the Previous Release of This Document, Added information on Apple Push Notification service (APNs), Integration with Apple Push Notification Service (APNs), Onboarding for Push Notifications via Apple Push Notification Service (APNs). Apart from the route pattern settings explicitly shown in Table 2-27 , all other settings are left with default values as shown in Table 2-28 . Endpoints covered include software-based endpoints, wireless and hard-wired desk phones, video endpoints, and analog gateways and interface modules for analog connectivity based on time division multiplexing (TDM). To simplify and provide consistent calling party presentation for all possible call flows, all calling party information received from outside networks such as the PSTN is normalized to +E.164 as discussed earlier. Therefore, you need to enable most of the Quality of Service (QoS) mechanisms available on Cisco switches and routers throughout the network. Deploy Cisco UCM Cloud with Webex Calling, UCM on-premises or 3rd party PBXs for optimized enterprise calling across your entire organization. With four or more clusters, deploy Cisco Unified CM Session Management Edition (SME) to centralize the dial plan and trunking and to avoid the complexity of a full-mesh SIP trunk topology. Table 2-51 shows an example of device pool settings for phones with video conferencing capabilities in site RTP. For more information about SME, refer to the Cisco Collaboration SRND. In addition to that, configure settings on IM and Presence servers: Enable availability sharing. Unified CM has an integrated database for storing user data and a web interface within Unified CM Administration for creating and managing user accounts and data. And Endpoints at these remote locations must be configured with an appropriate SRST reference within Unified CM so that the endpoint knows what address to use to connect to the SRST router for call processing services when connectivity to Unified CM subscribers is unavailable. When integrating a deployment of Unified CM and Unified CM IM and Presence Service with Apple Push Notification service (APNs), you can use Apple's cloud-bases Push Notification service to push notifications for voice and video calls and instant messages to Cisco Jabber for iPad and iPhone clients that are running in the background. Deploy the required number of virtual machines on your compute infrastructure using the appropriate Cisco provided OVA template files. Normal PSTN calls should make use of the primary and secondary site-specific PSTN resources defined for normal PSTN calls. In addition to GDPR, UDS-based service discovery used by Jabber also relies on the ILS exchange to detect the existence of UDS nodes on remote clusters to which /cucm-uds/homeCluster requests of non-local users can be forwarded to determine the home cluster of a user trying to log in to Jabber. Table 2-46 Example Unified CM Group Definition. All SIP trunks are assigned to route groups. A solid network infrastructure is required to build a successful Unified Communications and Collaboration system in an enterprise environment. To avoid the use of * also a number area starting with the abbreviated inter-site access code 8 can be used: for example 8000-. Other security aspects covered in this chapter include access control lists, securing gateways and media resources, firewalls, data center designs, securing application servers, and network virtualization. This creates problems with inter-server communications for example, Intercluster Lookup Service (ILS) and User Data Store (UDS) where the Tomcat certificate on the initiating side of the TLS connection is also used as a client certificate, and thus TLS connection setup fails due to the incorrect key usage (see the section Consider UDS Certificate Requirements). Table 2-38 shows an example of the country specific phone localization calling party transformation patterns that would need to be provisioned for Italy and Germany.
