-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 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!

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.

Umm, you've been doing duplicate work then.

The version of ozmod_isdn i have been working on is completely stateful and
has a couple of timers already implemented.

And i remember giving you the location of the git repository on IRC,
earlier this year. (But never got any feedback)

Well, I implemented just one timer by now. So not much time has been
wasted ...

Sorry, at that time we talked about q931 to pcap. By now I thought state
timers are still not done, so there wasn't a reason to test it regarding
state timers .... buuuut today things changed and I will download your
openzap.

regards
Helmut
