<p class=MsoNormal><font size=3 face="Times New Roman"><span lang=EN-GB
style='font-size:12.0pt'>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. <br>
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. <br>
<br>
