Hello Michael,

how much $$ are we talking about? I need this issue to be solved quickly
and it's worth to spend some money.

I've read the following post:

http://www.mail-archive.com/freeswitch-users@lists.freeswitch.org/msg05792.html
and have the same symptom with "after hundreds of calls I start to get b
channels that are stuck in states like "TERMINATING" or "HANGUP""

Best regards
Peter

I believe these are all symptoms of something that Stefan is working
on: better Q931 timers. It's been on the todo list for some time but
we've had absolutely NOBODY willing to pony up serious $$ to support
OpenZAP development which means it is progressing at the speed of
developers' free time.

When freeswitch is restarted or mod_openzap is reloaded, the error is
gone away.

Any idea what this can be?

Hello Michael,

thanks for your response. We have now decided (although this is not the
best solution) to put an Asterisk in front of FS who handles the Zap
stuff and passes it via SIP to freeswitch.
That way we got a stable zap configuration and the benefits of
freeswitch, although our IVR application is now respoinding a bit slowly.

I also do not have any developer with these skills in sight for fixing
these issues. Anyway I hope that we will overcome these zap problems
soon so that we can cme back to a pure FS installation.

Best regards
Peter

Peter,

I believe we are in a bit of a holding pattern right now with OpenZAP
PRI stuff. We have a super user, Stefan, who is working on some Q931
timers and such but he is working on it in spare time and there's no
hard date. If you know someone with serious PRI and C programming
skillz who can assist then we'd definitely be willing to have some
help. "Patches welcome" as it were. Smile

Thanks,

I did some more tests. When I sequentially setup calls (only one
simultaneous call at a time), it works for hundreds of calls.
As soon as I setup 2 calls in parallel ist fails aber a number of calls.

Please find another debug ouput (now with Q.921 debug also).
The log starts with the latest hangup of a successfull call. After this
one I receive a
"2009-01-15 20:26:46 [CRIT] ozmod_isdn.c:446 zap_isdn_931_34() Received

Is there anyone to fix it? May I donate some money for fixing that?

Thanks Helmut,

I cross-checked with our provider. They use national numbering plan for
our lines. So this didn't solve our problem.
I also ensured that the local language is DE and ZAP timing is dedicated
to span 1.

I changed the configs to debug mode for OpenZAP, so I hopefully will get
some more info on the next failure.

Best regards

Hi Peter,

it was simply a change in our TDM Voice Switch. It used a different
numbering plan and we changed it to "national" to get it work with FS
and openzap in Q921/Q931 mode.

What I still search is a way to configure the numberplan in FS.

To make it clear: In my case it didn't work from the second FS starts
up. So this differs from your problem.

To get an idea what's going on on the TDM link I used a TDM D-Channel
monitoring device and traced the d-channel messages exchanged between FS
and TDM. That should make it easier to see what's wrong when the
problems occur.
But you can also increase FS debug level to debug and trace the Q921
and Q931 messages in FS console via fs_cli during runtime. You have to
set this in openzap.conf.xml:

<param name="q921loglevel" value="debug"/>
<param name="q931loglevel" value="debug"/>

Unfortunately FS doesn't decode the whole Q931 messages, but it shows a
hex representation of the message, so you can manually decode it with
this documents:

Q.931: http://www.itu.int/rec/T-REC-Q.931-199805-I/en
Q.921: http://www.itu.int/rec/T-REC-Q.921-199709-I/en

I think for numberingplan issues you only have to track the Q.931
messages.

The last idea I have to get some light into your problem and to avoid
manually decoding, try to convert FS's q931 hexdump into wiresharks pcap
format. Wireshark should be able to decode it Smile

http://wiki.wireshark.org/Q.931

Maybe it's a good idea to implement a wireshark export for those
messages in FS. This will make debugging easy and cheap.

Hope it helps a bit.

regards
helmut

it must not be the case here, but I had the same error, when incomming
