Transfer problem - one way audio

I have a problem with transfering calls from PSTN to ITSP.

Situation is like this:

I have CCM 4.1, IPCC 3.5 and Cisco1760 GW. I have connection to one of ITSP-s which is working perfectly, but what I want to do is to transfer calls from PSTN to ITSP. After transfer there is only one-way audio, the called party cant hear anything.

I configured DSPFARM, command "h323-gateway voip bind srcaddr", voip rtp send-rcv. GW and CCM can contact ITSP router, so routing is OK. I would appriciate if someone can help me with this.

Try setting the CCM gateway to use MTP. I have seen this fix similar problems.

Thanks for response.

I alreasy done that, but it is not working. Basically, I have 2 GW in my CCM, one is my local Gw for PSTN calls and other one is ITSP router. I configured both GWs MTP required, Media resource group list . I put ACL on my VoIP intrface on GW , and after establishing connection, no packets are sent thru that interface. I think it should use that IP address as peer.
