[asterisk-users] No audio - using g729 codec altogether

[ast guy]

Hi,
 I am facing terrible issue regarding no audio/voice on both sides. I am
using g729 codec on two machines and carrier also supports g729 codec. I can
see the RTP traffic flowing but there is no audio.
Call is going from Server 1 to Server 2. I can see the established SIP
channels on Server but still no audio

C.L.M.37 = Global Address **-Server-1*
X.Y.X.55 = LAN Address of **-Server-1*
M.G.W.23 = Media Gateway of Carrier
A.B.C.136 = Global Address **-Server-2*


**-Server-1*

Any one has any idea why it is behaving so.
