[asterisk-users] asterisk 1.4.8 and google talk - no audio

[apnic apnic]

Hi all,

Iam using asterik 1.4.8 and connected to google talk. When iam calling from
my google talk account to sip phone i can hear the voice (2 way).  (this
happens only within the LAN).

when my friend tries to call my asterisk server (connects to the public ip)
using his googletalk client  it comes to my sip phone but either party cant
hear a voice.

I have fully allowd both tcp,udp on my router. and i have a public IP. (no
nat). i have disabled my firewall on my asterisk box (just for testing).

this is my configuration

gtalk.conf

bindaddr=147.120.203.190
externip=203.xx.xx.xx
