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.

IM and Presence Service now has an enhanced mechanism of advertising XMPP stream features/services (mdm:1, push:3, and so on) to the clients connecting over Cisco Expressway's Mobile and Remote Access (MRA).

The new design supports deployments consisting of IM and Presence clusters with mixed versions. For example, some IM and Presence clusters run 11.5(1) SU7 and some clusters are upgraded to 11.5(1) SU9. This ensures that the client always gets the correct list of supported or enabled stream features from the version of the IM and Presence server that the end user is assigned to.

For this mechanism to work, the minimal deployment requirement is to have Cisco Expressway running version not older than X12.7, and to have at least one IM and Presence cluster in the intercluster mesh running version 11.5(1) SU9 or above.
