please make sure you stay tuned into #openzap and coordinate with stkn and the other guys<br>doing work on the stack. That way we can make sure we get the best out of the code.<br><br><br><div class="gmail_quote">On Fri, Jun 12, 2009 at 9:32 AM, Helmut Kuper <span dir="ltr"><<a href="mailto:helmut.kuper@ewetel.de">helmut.kuper@ewetel.de</a>></span> wrote:<br>

Hello,<br>
<br>
I just want to let you know, that I started some work on Q.931 TE state<br>
timers in current openzap ozmod_isdn stack. The current stack has some<br>
problems with freeing ressources when far end doesn't follow Q931 state<br>
machine cleanly. On my side I mainly miss a RELEASE after sending<br>
DISCONNECT and so m more and more channels are wasted over time.<br>
<br>
Openzap Q931 stack has some preworked timer and state handling (in form<br>
of Q931_UX states). Unfortunately it is disabled in source. I enabled<br>
it, added some Q931_UX states to Q931StateTE.c, added a timeout handler<br>
to ozmod_isdn.c and tested it with my special problem. In lab missed<br>
RELEASEs are now detected and the corresponding channel is freed cleanly<br>
- - hurray :)<br>
<br>
I would like to put my work in openzap trunk as soon as it works stable<br>
in production and FS board allows me to do so.<br>
<br>
I can't promise that I will implement all timers for Q931 TE nor I plan<br>
to work on Q931 NT timers.<br>
<br>
As I said: Just for your information.<br>
<br>
<br>
Have a nice weekend!<br>
<br>
Helmut<br>
