asterisk users - Feb 2016 - Ignoring audio media offer because port number is zero

Hi,

I'm trying to setup a sip trunk. The asterisk version is Asterisk
certified/11.6-cert12. I had to change the CallerID to a pilot number of
the trunk as provider only accept it. but when i dial I'm getting below
error. Cannot hear anything

[Feb 11 14:19:45] WARNING[3920][C-0000005d]: chan_sip.c:9978 process_sdp:
Ignoring audio media offer because port number is zero
[Feb 11 14:19:45] WARNING[3920][C-0000005d]: chan_sip.c:10367 process_sdp:
Failing due to no acceptable offer found


Any suggestions to fix this issue? Please help

Best Regards,
Madushan

and this is working without any issue in elastix. I need to setup this in
pure asterisk installation.
