Hi Amr, Just recreated the scenario.
When I call into MVA and transfer to 1002 (g729 from HQ), the call rings and when I answer it it drops. The reason for this i believe is the g711u codec setting on the dial-peer. So I added a voice class codec with 711 and 729 on the HQ GW and applied it on the incoming mva dial-peer. In this case I can ring and answer on 1002 but there is no audio. I am clueless at to what else to try. And yes when I change the codec between hq and br1 to 711 it works fine.
