[asterisk-dev] Code Support request for IAX provider sending registration refreshes of 0

[James Trix]

Well I throught I would trace a session with the Tesco desktop client
and see what i could see. I created a packet trace with good old wire
shark and from what I can see is  that tescos does send a refresh
registration: 0

But it looks like the desktop client just does a IAX2 ping every few
seconds and then a ACK comes back from the povider.

Asterisk does not send this IAX2 ping back and after about 1 minute
the connection drops off. So i guess my questions are could some one
comfirm that is what is happening in the capture that can be seen here
http://pastebin.com/823208 and if so what can i do ? rebuild Asterisk
and then do a ignore on registration: 0 ? or could I write some sort
of IAX2 ping and set a cron job to send out a ping every 60 seconds ?

Any ideas right now would be good :-)
