Summary:                    [Help] no voice after call get connected in g729
codec
Description: 
I setup a asterisk environment with the sip trunk and the codec used is
g729. For some of the  calls, after call connect there is no voice and it
is  blank. This is happening for 30% precentage of calls. I written a
dialer Application in AMI, it will make the outbound call with one
particular number and the call will be connected to the available SIP
extension.
 
Asterisk - 1.4.24.


I purchased 151 licenses of g729.
Specification : 64bit
codec_g729a-1.4_3.0.3-nocona.tar.gz
Ouptut of show g729 CLI command.

2/4 encoders/decoders of 151 licensed channels are currently in use.

and the phone which i am using is Cisco 7940 and it support the g729
codec. The problem is 30% of calls are no voice calls. I am using the
FreePBX for asterisk administration. Please Kindly direct me in right
direction.

Thanks in  Advance,
balasam
