please make sure you stay tuned into #openzap and coordinate with stkn and the other guys doing work on the stack. That way we can make sure we get the best out of the code. On Fri, Jun 12, 2009 at 9:32 AM, Helmut Kuper <helmut.kuper@ewetel.de>wrote:

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