[asterisk-users] Asterisk and the media path

[David Wessell]

All g711 calls, and the only nat is on the endpoint.

Snom M9 Phone (behind nat) -> PBX (Public IP) -> LCR Trunk (Public IP)
-> SIP Provider (Public IP)...

I'm expecting the LCR trunk to get out of the media path and connect
the PBX with the SIP Provider....

Thanks
David
