[cisco-voip] CUCM Failover/Failback Call Drops

[William Roy]

I was missing a command that fixed this issue:

!
voice service voip
 h323
  call preserve
!

We are testing CUCM redundancy and are having issues with the following scenario. CUCM 6.1.2 cluster with a publisher one subscriber and a h323 gateway.


*         IP phone is registered with  SUB

*         We make a call to an external phone via H323 gateway

*         We fail the SUB - the call is maintained

*         While still on the same call we bring back the SUB

*         After a few moments the call drops

Is there away to prevent the call dropping?

Regards
Wil
