Hi Community
My client has two CUCM clusters ( One is Version 7.00 and Other is 11.0) trunked over a SIP trunk recently. Both clusters are at the same physical location. The first cluster has H.323 Gateway which is connected to PSTN over E1-PRI. The second cluster uses the first cluster as transit to go out to PSTN.
PSTN<-----------------H.323 ------------------------>Cluster1<>----------SIP--------------<>Cluster2

Use1(Ext1) User2(Ext2)
This deployment is in the testing phase and we are facing the following issue-
When User1(Ext-1) Call forward his extension ( call forward all) to user 2 (Ext 2) and someone from PSTN calls user 1, Call follows the call forward all path and rings Ext-2 /User2. If user 2 pics the call the speech path does not establish. I suspect it to be a media negotiation issue. Our gateway supports G.711 codec and we do not have any Transcoder in the environment. Can anyone suggest anything on this?
Regards
Ashwin
