I have successfully installed Asterisk 11. It works fine, but there is a problem with the Gtalk integration.
This problem may occur with clients that are behind NAT, server Asterisk I get the following message from google:
<— XMPP received from ‘google’ —>
<candidate name=“rtp” address=“172.16.12.199” port=“35748” preference=“1” username=“u0xF65G8h21ORauz” protocol=“udp” generation=“0” password=“xYXn2V6Wq1EEm04k” type=“local” network=“wlan0”/>
Actually Asterisk does not understand where to direct rtp stream, because It does not receive information about the white ip address where to send the call.
In prior Asterisk versions, I had to have the line “externip” in the [general] section of gtalk.conf for it to work properly.
I googled this problem, and found many questions like this, but no one solution.
For example on old asterisk forums
exten => s,1,NoOp()
;exten => s,n,Answer()
exten => s,n,Wait(2)
;exten => s,n,SendDTMF(1)
exten => s,n,Dial(SIP/testclient,20)
;exten => s,n,Playback(demo-congrats)
