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

[Benjamin Amezcua]

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,
