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

Ouptut of show g729 CLI command.

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,
