Hello,
I have problem with g729. In sip_general_additional.conf I have this
; do not edit this file, this is an auto-generated file by freepbx
; all modifications must be done from the web gui
vmexten=*97
disallow=all
allow=ulaw
allow=alaw
context=from-sip-external
callerid=Unknown
notifyringing=yes
notifyhold=yes
limitonpeers=yes
tos_sip=cs3
tos_audio=ef
tos_video=af41
When I insert allow=g721 it`s OK but after few seconds free PBX change sip_general_additional.conf and disallow g729
