hi guys,
running cucm 11.5 with expressways X8.11.4 (both e and c are a cluster deployment). jabber MRA via exp c 1 was registered to cucm and working fine (Jabber is registered on cucm with exp c1 ip add). we decided to test the MRA failover by shutting down the exp c1. The expectation was that it would register with cucm with exp c 2 IP add. it didn't register as expected for some reason. if we log out of MRA jabber while exp c1 is down, it will then register with cucm using exp c 2 ip add. it seemed that a manual log out/login required to make it work.
so my question is should it automatically fail over to secondary exp c2 when c1 is down? if yes, I am not sure why it didnt failover to expc2.
thanks a lot

I did wait way over 10 minutes for auto reregistration which didnt happen. Thats when i logged off and logged back in.

I also notice this issue, putting an expressway c of a cluster into maintenance mode. The Jabber does not failover to register via the other expressway c. Just remains unregistered until a restart of Jabber (waited 10 mins). The cucm service parameter SIP Station KeepAlive Interval is set to the default of 120.

i dont have access to play around and figure out why this happened. but if you have access to Expways for testing then you can modify these values and test again pls.
go to exp C configuration->protocol->sip-> and you will see these.
Outbound registration refresh minimum” : 300 seconds
“Outbound registration refresh maximum : 3600 seconds
you can change the mininum to 30 sec and maximum to 60 sec. (or 60 and 120 sec) and test again. if it doesnt help you can put back to original settings. thanks.

Failover scenarios are currently not supported. Not supported means that some scenarios might work, and some others don't. As an example, failover works for hardware endpoints. This will be fixed in the next major release, X.14, but might require an UCM upgrade.
