Dear Community
These has being mentioned many times over and is documented on issue id CSCuq79072. I also experienced it first handed few years back.
According to Cisco MRA Deployment Guide , Cisco does not support failover for any service except IM&P on jabber. Recently i have being testing with jabber (12.1.1.269866) and latest CUCM (11.5(1)Su5) and Expressway (8.11.2) and i was surprise to find out that jabber is able to failover to secondary CUCM when primary was turned down. Cisco said is not "supported" because is "inconsistent" o even not possible because of how client use TCP to connect and detect failure
The interesting piece is that jabber shows being register in one CUCM and CUCM GUI reports another but calls can be routed successfully.
Does somebody else has similar experience?
Thanks
Alex
