[cisco-voip] Jabber via MRA failover from one CUCM node to another

[Gerence Guan]

Hi All,

I found this old post from Cisco community.
https://community.cisco.com/t5/ip-telephony-and-phones/jabber-softphone-via-mra-does-not-fall-over-to-secondary-cucm/td-p/2807099


Is this still true for Jabber 12.8, MRA 12.5 and CUCM 12.5?

In the MRA 12.6 deployment guide it says
Cisco *Jabber* clients support IM and Presence Service failover over MRA.
However, they *don't support* any other type of MRA-related redundancy or
*failover*—*including SIP*, voicemail, and User Data Services (UDS).
Clients use a single UDS server only.

In the Jabber 12.8 planning guide, it says High Availability(failover) of
audio and video service is not supported

If anyone has a MRA lab, can you please help to test it buy just disconnect
the first cucm node in the jabber's ccm group and verify whether jabber can
register to the second node in the ccm group?

This is a surprise to me that this fundamental feature is still not
supported after many years.

Best Regards
Guan
