Before you upgrade to Release 12.5(1) or above, we recommend that you work with your channel partner or account team to use the Cisco Collaboration Sizing Tool to compare your current deployment to an upgraded 12.5(1)SU7 deployment. If required, change VM resources to ensure that your upgraded deployment provides the best performance.

New and Changed Features

Centralized Call History

With this release, Webex Calling for Microsoft Teams users can view the call history for their shared devices which are registered to the Unified Communications Manager.
For more information, see Webex Call Integration with Microsoft Teams for On-prem UCM.
To use this feature, the Unified Communications Manager node must be onboarded through Webex Cloud-Connected UC.
Microsoft Teams users must use Webex Calling integration for Microsoft Teams.

Note

This feature has dependent services which would be available later. For more information, see Webex Calling integration with Microsoft Teams.

Cluster Software Location Updates

Unified Communications Manager now makes it easier to specify where cluster nodes will find their ISO files for upgrade or COP files, using the Cluster Software Location menu from the Cisco Unified OS Administration user interface. In this release, you can centrally manage the Software Location settings for all cluster nodes from the publisher instead of locally on each cluster node.

User Interface Updates

To support the feature for this release, the following menu items are updated:

You can add, edit, or modify any of the existing configurations for any node in the same cluster by navigating to the Software Upgrades > Cluster Software Location menu item in the Cisco Unified OS Administration user interface.
Fields in the Software Installation and Upgrade menu item is now enabled for editing.

For detailed information on the new parameters and fields, see the Cisco Unified OS Administration Online Help.

CLI Update

If you want to modify the existing Software Location configurations for any node in the same cluster, either use the CLI prompts on the local node or quit and login to use the Software Upgrades > Cluster Software Location menu from the Cisco Unified OS Administration user interface of a Unified CM publisher. To install upgrades and COP files from both local and remote directories for a single node or cluster nodes, use the following commands:

utils system upgrade
utils system upgrade cluster

For more details about the CLI commands, see the “Utils Commands” chapter in the Command Line Interface Reference Guide for Cisco Unified Communications Solutions.

Eliminate Refresh Token Dependency on Publisher for OAuth

OAuth feature is now enhanced to eliminate refresh token dependency on Unified Communications Manager publisher node by providing access to the subscriber node to update the refresh token. For more information, see the ‘System Parameters Task Flow’ section of the “Configure Enterprise Parameters and Services” chapter in the System Configuration Guide for Cisco Unified Communications Manager.

Emergency Calling for National Suicide Prevention Lifeline

Unified Communications Manager supports dialing ‘988’ calls, that are 3-digit dialing codes that will be routed to the National Suicide Prevention Lifeline centers. All telecommunication carriers and interconnected voice over Internet Protocol (VoIP) service providers will offer this service to connect with suicide prevention and mental health crisis personnel. This is in support of the FCC mandate of supporting a 3-digit dial code for Suicide Prevention Hotline that comes into effect from July 22, 2022.

For more information, see: https://www.fcc.gov/suicide-prevention- hotline.

JTAPI Compatibility with Emergency Responder Release 14SU2

Cisco Emergency Responder (Emergency Responder) Release 14SU2 is now backward compatible with Unified Communications Manager Releases 14SU1, 12.5.x, and 11.5.x.

Important Notes

Default CA Certificates During New Install and Upgrades

After you install Unified Communications Manager Release 12.5(1) and above, all of the default CA certificates except for the CAP_RTP_001 and CAP_RTP_002 certificates are present. You can enable these certificates using the set cert default-ca-list enable { all | common-name } command. If you are upgrading to Unified Communications Manager Release 12.5(1) and above, only the default certificates that were present in the older version appear after the upgrade.

Disabled Default Certificates Backup Fails

When you perform a backup using Disaster Recovery System (DRS), if all or specific default certificates are disabled using set cert default-cal-list disable {all | common-name}, then backup does not contain disabled certificates. When you are restoring the backup on the fresh installed server, those disabled certificates reappear.

ILS Networking Capacities

The Intercluster Lookup Service (ILS) network capacities have been updated for Release 12.5(x) and up. Following are the recommended capacities to keep in mind when planning an ILS network:

ILS networking supports up to 10 hub clusters with 20 spoke clusters per hub, up to a 200 total cluster maximum. A hub and spoke combination topology is used to avoid many TCP connections created within each cluster.
There may be a performance impact with utilizing your hub and spoke clusters at, or above, their maximums. Adding too many spoke clusters to a single hub creates extra connections that may increase the amount of memory or CPU processing. We recommend that you connect a hub cluster to no more than 20 spoke clusters.
ILS networking adds extra CPU processing to your system. When planning your hub and spoke topology, make sure that your hub clusters have the CPU to handle the load. It may be a good idea to allocate systems with high CPU utilization as spoke clusters.

Note: The above capacities are recommendations only, based on system testing. Unified Communications Manager does not enforce a limit, either on the total number of clusters in an ILS network, or on the number of spoke clusters per hub. The above topology is tested to ensure optimum performance so that the system does not burn too many resources.

For additional information on ILS, see the ‘Configure Intercluster Lookup Service’ chapter in the System Configuration Guide for Cisco Unified Communications Manager.

Java Requirements for SAML SSO Login to RTMT via Okta

If you have SAML SSO configured with Okta as the identity Provider, and you want to use SSO to log in to the Cisco Unified Real-Time Monitoring Tool, you must be running a minimum Java version of 8.221. This requirement applies to 12.5(x) releases of Cisco Unified Communications Manager and the IM and Presence Service.

Multiple Clock-Rates Not Supported in Same Call

With this release, Cisco TelePresence endpoints and Cisco Jabber clients do not support multiple “Telephone-Event” SDP attributes with different clock rates to match the offered codecs. This capability is required to interwork with VoLTE/IMS endpoints fully. Due to this update, interoperability issues between these endpoint types and VoLTE or IMS endpoints may arise for mid-call reinvites where a different clock rate from 8 kHz is negotiated. For calls between these endpoint classes:

The initial call setup occurs without any issues.
Mid-call Re-INVITE will see no issues if the invite is initiated by Unified Communications Manager.
Endpoint-initiated reinvites may see interoperability issues if they use a different clock-rate than 8 kHz.

New Cisco Gateway Support

New releases of Unified Communications Manager have introduced support for the following Cisco gateways:

Cisco VG400 Analog Voice Gateway
Cisco VG420 Analog Voice Gateway
Cisco VG450 Analog Voice Gateway

SDL Listening Port Update Requires CTIManager Restart on all Nodes

If you edit the setting of the SDL Listening Port service parameter, you must restart the Cisco CTIManager service on all cluster nodes where the service is running. Currently, the help text says to restart the service, but does not specify that you must restart the service on all nodes where the service is running. You can access this service parameter from Cisco Unified CM Administration interface by navigating to System > Service Parameters, selecting Cisco CTIManager as the service, and clicking Advanced to see a complete list of CTIManager service parameters.

This update is a part of CSCvp56764.

Export Control with Satellite Deployment for Export Restricted Customer

Unified Communications Manager supports Export Restricted Customers to enable Export Control functionality on Unified Communications Manager with Satellite Deployment (Satellite Version: 7-202001). See the ‘Smart Software Licensing Overview’ section in the “Smart Licensing Export Compliance” chapter of the System Configuration Guide for Cisco Unified Communications Manager. For more information on Satellite, see https://software.cisco.com/download/home/286285506/type/286285517/os.

Upgrade Database Schema from IM and Presence Release 11.5(1) and Above

If you have Microsoft SQL database deployed as an external database with the IM and Presence Service, choose either of the following scenarios to upgrade the database schema.

Table 6: MSSQL Database Schema Upgrade Scenarios

Scenario	Procedure

Upgrade from IM and Presence Service 11.5(1), 11.5(1)SU1, or

11.5(1)SU2 release

| For more information on how to upgrade your MSSQL database, see the ‘Database Migration Required for Upgrades with Microsoft SQL Server’ section in the Database Setup Guide for the IM and Presence Service.

This makes the necessary changes to the column types from TEXT to nvarchar(MAX).

Upgrade from IM and Presence Service 11.5(1)SU3 or later| The MSSQL database connected to the IM and Presence Service Server is upgraded automatically during IM and Presence Service upgrade. This makes the necessary changes to the column types from nvarchar(4000) to nvarchar(MAX).

Note If you want to trigger an upgrade manually for any reason, such as to connect to an older database with column type as nvarchar(4000), the following actions trigger and upgrade the database by changing the column type to nvarchar(MAX):

• Restarting Cisco XCP Config Manager followed by restarting Cisco XCP Router service; or

• During schema verification of the external database—when you assign the database to Text Conferencing (TC), Message Archiver (MA) or Asynchronous File transfer (AFT) services, and reload the External Database Settings page. (From the Cisco Unified CM IM and Presence Administration user interface, choose Messaging > External Server Setup > External Databases, and then find and select the database to load the External Database Settings page.)

Unresponsive Remote Cluster Nodes

Problem

All nodes of the remote cluster are down at once.

Description

If in the preceding problem,

We have two clusters with four nodes each and all nodes on both clusters are UDS configured.
Cluster 2 is defined under Cluster 1 view with Publisher FQDN and conversely, the Jabber user has home cluster as Cluster 1 but SRV points to Cluster 2, then Cluster 2 holds all the entries of RemoteClusterServiceMapDynamic table that are initially updated when FQDN of Publisher from Cluster 1 is configured under Cluster View was reachable.
If all three nodes of Cluster 1 under RemoteClusterServiceMapDynamic of Cluster 2 are down at once due to an outage, the new Jabber login fails to discover the home Cluster.
Even when the nodes are down, RemoteClusterServiceMapDynamic on Cluster 2 continues to display the previous IPs.
Cluster 2 automatically updates the entry of the next node in the list with UDS active, if the nodes are brought down sequentially or one node from RemoteClusterServiceMapDynamic, goes down.

The problem is when all 3 nodes from Cluster 1 which are under RemoteClusterServiceMapDynamic are down due to an outage, the 4th node doesn’t get added to RemoteClusterServiceMapDynamic. However, if you point a responsive Cluster View of Cluster 2 to an active Subscriber on Cluster 1, then RemoteClusterServiceMapDynamic is updated automatically.

Solution

Delete the inactive remote node from the cluster view and add an active node.
This update is a part of CSCvq5867

Restart Cisco Tomcat Service

We recommend that you restart the Cisco Tomcat service after enabling or disabling Security Assertion Markup Language Single Sign-On (SAML SSO).
