I recently added G729 licenses to one of our Asterisk servers. When a call connects with G729 , DTMF ceases to be recognized by the Asterisk system.
I have tried auto and rfc2833 for dtmfmode. Here is a copy of the sip.conf
[general] port = 5060 ; Port to bind to (SIP is 5060) bindaddr = 0.0.0.0 ; Address to bind to (all addresses on machine) disallow=all allow=g729 allow=ulaw allow=alaw relaxdtmf=yes dtmfmode=auto ;dtmfmode=rfc2833 canreinvite=no qualify=yes jbenable=yes t38pt_udptl=yes ; Default false context=from-trunk ; Send unknown SIP callers to this context tos_sip=cs3 tos_audio=ef progressinband=never subscribecontext=ext-local limitonpeers = yes
I have tried searching google and this forum for possible answers. Has anyone else using G729 encountered this issue and if so , could you point me in the right direction to resolve this?
