Gtalk connected with asterisk but no network and audio

Hello
I have suceesfully connected gtalk through asterisk but problem of no audio from both sides.
also I saw network =“0” in asterisk log and no signal comes in gtalk.
Don’t know what I made mistakes. using Asterisk 10.3
Here is my conf and asterisk cli log.

gtalk.conf
[general]
context=google_talk_in
allowguest=yes
bindaddr=X.X.X.X
disallow=all
allow=g729
allow=ulaw

[guest]
disallow=all
allow=g729
allow=ulaw
context=google_talk_in

Nobody knows what is the prob and how to resove this?
why didn’t I get audio ?

thanks in advance

Are you loading the necessary codec modules? At a minimum you should have codec_ulaw.so and codec_gsm.so being loaded by your modules.conf. If you don’t have the necessary codecs you’ll see alot of messages about missing codecs if you watch your asterisk console while you’re making a call.

It also might have something to do with who you’re calling. Right now my gtalk calls to sprint and at&t users work, but when I call verizon users, they cannot hear me. (I’m in the US)

thanks briankb for reply
But don’t know whats the real problem
I tried to calling by asterisk version 1.8 and it perfectly fine (I heared audio too)
but no help with asterisk 10.3 (same configuration in both).

May be asterisk developers know.
