H.323 Gateway

[PeTaKkI]

I have ccm 4.2 in my network, and i´m trying to connecto with a pbx panasonic tda200. I have configured it as a H.323 Gateway, and it works well (send signalization, establish the communication...), but the ip phone receive no rtp packets. I think it can be becasue the pbx send rtp packets to CCM ip, not to ipphone ip.

But I have another problem i can´t understand. The CCM is conected to a 2801 as a MGCP Gateway, and the 2801 has a vwic2fxs with a analog phone. If I call from PBX to analog phone on fxs port (or from analog phone to pbx) it works properly.

The last problem is that form PBX I can´t hear ringing tone.

Can anyone help me?

I have viewed the packets transmision between de cisco call manager and the panasonic pbx (h.323 gateway). The problem is that when ccm transmit the h.225 packet to request the logical connection it sends its own ip address instead the ip phone address, so the pbx, when the connection is stablished sends the rtp packets (voice traffic) to the call manager ip.

And now, has it got any solution? Is this a configuration problem? Are Panasonic PBXs incompatible with Cisco Call Manager 4.2(3)? And if Cisco has implemented the h.323 protocol wrong...

I wonuld configure your Router as a gateway and route the calls to there. on the gateway configure your dial-peers to route accordingly 1 to the pbx and 2nd to ccm. dont forget to do your h323 bind on an nioterface and this will overcome loss of rtp streams.
