[asterisk-users] No Audio with Gtalk

Well I found out what the reason is. When the gtalk client is behind a 
NAT it will not work (at least for me it doesn't).
Citing from : 
http://www.google.com/support/talk/bin/answer.py?answer=27930&query=udp&topic=&type=

gtalk needs either UDP connections to anywhen on any port
OR
TCP Connections to anywhen on port 443.

For me the only way to get it to work has been to open the UDP ports, 
which is unacceptable for day-to-day use.

Check out these bug reports for more on the subject: #7686 #8193 and 
#8655. None of the proposed bug fixes have worked for me though - and so 
I have given up for the time being.
