[Asterisk-Users] H323 -- No Audio

[Leah Newmark]

I am attempting to set my outgoing calls through H323, however once the call 
is picked up, no audio works on either side.

Any suggestions?

H323.conf
--------------
[general]
port = 1720
bindaddr = 0.0.0.0
disallow=all
allow=g729
allow=gsm
dtmfmode=rfc2833
gatekeeper = 63.208.156.185

Extensions.conf
-------------------
exten => _91XXXNXXXXXX,1,Dial(H323/${EXTEN:1}@63.208.156.185)


Is there another codec I need in H323?
