I have a single site on a Panasonic PBX and three remote site on Cisco CME.
I configured the remote sites with a voip dial-peer pointing to the PBX IP Address. I have a problem with a single site.
The problem can be broken down as follows:
IP Phone -> Analog = Ringing then the call disappears from the "voice call status" as the user picks up
Analog -> IP Phone = Ringing then as the IP Phone picks up, and I see "Connected" on my IP Phone but the "show voice call status" shows none in the codec column indicating that it's not picked up yet and all the while the the analog phone is hearing ringback and the IP Phone hears MOH tone !!!!!
I have changed the codecs repeatedly even from the PBX side but still no luck. I now have a voice class with all the codecs
There are firewalls at each site but I've set policies to allow H323 and RTP between them.
I'm sure I'm not hitting any bug or anything as one of the working remote sites have the exact IOS image and CME version.
In all cases I have hardware transcoders configured and they seem to be registered.
