asterisk users - Apr 2005 - sipura 3000 - "Call Leg/Transaction Does Not Exist" - only happens sometimes

Here is my problem 

I have an incoming call on the FXO port of the Sipura 3000 this goes to
my asterisk box (running CVS - head) and then by default goes back to
the sipura 3000 on the fxs tel port.


Every 5 or so calls when the call is picked up on the fxs port telephone
I just get beeping  and on the asterisk console it comes up with

Got SIP response 481 "Call Leg/Transaction Does Not Exist" back from
xx.xx.xx.xx

Anyone else had this problem?

Yes, I used to see this problem from time to time as well. I'm not 100%
sure, but I think it was caused by someone dialing in to my Asterisk
box, then hanging up at the menu and the SPA3K not detecting the hangup,
or at least not sending it to Asterisk. 

But when either another call comes in, or a outgoing call is made, the
SPA3K happily accepts it and works as normal, leaving Asterisk to think
there are two calls going through the SPA3K, when it fact only one is,
thus the "Call Leg/Transaction Does Not Exist" message.

The way I resolved the issue was to put a absolute timeout in my menu
(which I should have always had anyways) and upgraded the firmware of
the SPA3K. Since then I haven't "noticed" the issue, but it
hasn't
negatively affected anything so I'm happy with it.

Just a guess... you might try adding canreinvite=no to the sip.conf
definitions.
