[cisco-voip] Cisco Panasonic Integration

[David García Ternero]

Hi,

 

I am trying to integrate a Cisco Call Manager 5.1 with a Panasonic PBX with
a H.323 IP card, using Cisco IP Phones and Panasonic analog phones. To do
that, I have configured the Panasonic IP card as an H.323 Gateway in the
Call Manager, and I route the calls to the Call Manager in the Panasonic
PBX. The call establishment seems to proceed ok, and you can call in both
directions. But there is sound only in the Panasonic phone, and not in the
Cisco phone, because the voice stream goes from the Panasonic IP card to the
Call Manager, instead of going to the IP Phone. I have some traces of the
traffic and I see that in the h.245 open logical channel message, the Call
Manager includes their own IP address, instead of the IP address of the IP
Phone, but in the open logical channel ACK message, the call manager
includes the IP address of the IP Phone. 
Is it a bug in the implementation of the protocol? are there any mistake in
the configuration? I have a Cisco 2801 CCME that maybe can help in the
deployment. 

Thanks

 

David García Ternero
