Hi all,
When I am making call with with my Cisco 7960 SIP phone, I
found only codec g711 works.
The network call is like this:
CISCO AS5300 ---sip----> Asterisk ----sip--->
CISCO7960
Peer
User/ANR Call ID Seq
(Tx/Rx) Format

following config in sip.conf
allow=g723
allow=g729 allow=gsm allow=ulaw allow=alaw However, it seems that
only codec gsm work fines. However, it still occupy more bandwidth.
Just would like to know if asterisk can do codec g723 or g729?
Anyone has
encountered this problem or am I missing any config in asterisk?
Thanks.
Raymond
