Hi Kshitij, Thanks for the great explanation.I have one doubt regarding case1.
In case 1 (call coming from PSTN to branch phone) when we have not defined any codec on voip peer then by default g729 codec will be selected and it seems G729 codec finally used to connect to phone irrespective of fact that branch gateway and branch Ip phone are in same region. Show voice call summ on brach router shows that call connected using g729 and MOH to PSTN caller will not work in this case when CUCM is multicasting MOH (no multicating from branch router) as g729 codec is not supported. Same MOH/multicasting works when voip dial-peer codec is forced G711. PSTN ------------GW ------G729 ------CUCM--------g729----- IP PSTN---------- GW-------------------------G729-------------------IP Phone The reason for g729 codec used seems to be fact that this codec is used by GW voip dial-peer as default (only option) and now CUCM will negotiate codec with IP phone using sccp keeping in view that one leg is g729 so final selection will be g729. If this is the case transcoder should be invoked to send call to Ip phone. Has someone tested this in lab scenario. Regards, Brajesh.
