[asterisk-users] G729 Passthrough How To

[Asghar Mohammad]

As my understanding Asterisk always pass-thu g729 if both ends have this
codec.
But if you answer the call or play some audio before dialing to end point
then asterisk stay between both legs.
In case of VM. you should install g729 if your prompts are in g729 format.
As a2billing play voice prompts you cannot pass-thu transparently.
I think the load on you server is not for transcoding  but PHP scripts.
I was in this situation and reduce the upto 80% by removing A2B.
