[asterisk-users] Automatic Hangup problem on IAX2 communication to Asterisk

[Rajiv Dhir]

Hi all,

I'm having a problem with receiving calls from a VOIP provider who is 
providing inbound PSTN termination using IAX2 to my asterisk at home 2.6 box.

The box is a mini-ITX based P5000 system running off a 2.5in drive with 
a digium TD400P (3 FXO). But this problem does not relate to the card.

Basically the provider gets a call in but when he talks to my server the 
two don't establish a call. At the same time as this happens I am able 
to access my system using my Digium IAXY.

I turned the IAX2 debugging on at the console and this is kind of what I 
see.

The provider gets a call and sends a frame to open the call.

I then take 13ms to send a "Challenge" request back to him.

By this time he seems to have sent a retry at 10ms.

At this point he then receives the challenge but sends back an "INVAL" 
which causes a hangup. This process repeats until the PSTN is hung up.

Am I right in thinking there is a timeout here and this is causing the 
problem?

I enclose the debug log. Any help appreciated. I've replace the actual 
phone numbers and ips for obvious reasons


Any Help appreciated, as I seem to have gone off the end of my service 
providers knowledgebase.

Cheers

Rajiv
