echotest with Asterisk + x-lite

Posted:Tue 02 of Aug, 2011 (19:46 UTC)
Hello everybody

I need your help. I am a beginner with SIP. I have been struggling this issue for more than a day and still could not solve it.
What I am doing is very simple to get echotest work with x-lite and asterisk. My x-lite can connect to asterisk server and I can hear the echo. But after about 32 seconds, the connection got disconnected. And I got a warning message said "no reply to our critical packet", please see below.

It seems to me there is some wrong with my config. But I just couldn't figure it out.

I am using X-lite 4.0 for mac
Asterisk on a Linux box with a static IP.

Please help


Here is my Asterisk setting
callerid="" <9990002>

exten => _X.,1,Answer()
exten => _X.,n,Playback(demo-echotest)
exten => _X.,n,Echo()
exten => _X.,n,Playback(demo-echodone)
exten => _X.,n,Hangup()

I am using x-lite 4.0 for mac.
