[cisco-voip] RTP problem with H323 integration between CCM 5.0.4and panasonic TDA30 with IPGW4 Card

[Ryan Ratliff]

It depends on why the Panasonic is sending RTP to the CM.  You can try
setting the "MTP Required" box on the trunk/gateway configuration in
CCMAdmin but this may or may not work, and assumes you have an MTP resource
that can be invoked.

On an unrelated note you should really not be running CUCM 5.0(4). I'd
recommend an upgrade to 5.1(3b) or later.

Hi All,

We are trying to have a H323 trunk between a CCM 5.0.4 and a hybrid
Panasonic TDA30 with IPGW4 card. Signalling work fine and we call init a
call between analog phones(in the Panasonic side) to/from Cisco 7906. 
The problem is that the user can listen to the other side in the Panasonic
phones but no in the cisco phones.

We have made a sniffing in the network and we see that the cisco phones
sends rtp traffic to the Panasonic pbx (this is ok!) but the Panasonic pbx
sends the traffic to the CCM (and not to the other end(the cisco phone)).

Is there any way to configure CCM to work like a RTP proxy and resend voice
packets to the cisco phone? 

I will appreciate any help.
Regards,

Benjamin Amezcua
