Hi all experts.
I have a very simple scenario. I have one 3845 router and CUCM 7.x. I have taken SIP trunk from our local ITSP. The calls will be coming using g.711 codec. Now i have 20 branches, all of them using g.729 over WAN and our HO (where 3845 with sip trunk from ITSP is placed) is using g.711 codec on LAN. As you can see, so far its very simple. I want to ask, that if a call comes from outside (over SIP trunk) to any branch extension(which is using g.729), is transcoding required ? since call is coming from g.711 and going for g.729 extension !!
Kindly guide me
