I am calling from an IP phone to simulate an incoming call to the environment.
The numbers I am calling are defined on teh SIP server.
If I call the number defined on the location A SIP server, call establishes without any problems.
If I call the number defined on the location B SIP server, I can hear the announecements, call establishes, but at the end no audio onboth ways.
*** During this call without audio, if I receive a call from someone else ( internal ) and put the first call on hold, when I resume it, I start hearing audio both ways. Sometimes very clear, sometimes with a lot of noise.
I am sure about the routing and firewalls. All the phones and trunks, etc in location A is in DP_A device pool, all the phones and trunks, etc in location B is in DP_B device pool. Their regions are configured so that, in each DP they will be using g.711 and in between device pools, g.729.
If I put everything in the same DP, both scenarios work perfectly.
I atttached the config of one of the voice gateways in location B ( all 4 of them have exactly the same config , I tried two IOS versions without success )

what they mean. This document attempts to br...
