Hello,

since yesterday I do a real life test with FS in a 40 sip extension
environment with TDM connection via wanpipe/sangoma A104d.

I detected two times the problem, that openzap stops working, while SIP
calls worked. Only restarting helped. Maybe reloading of mod_openzap
helps as well, but I didn't tested that, yet. I filtered FS logfile for
hints of that problem and I found a growing number of this line:

2009-02-06 11:09:51 [INFO] ozmod_isdn.c:706 zap_isdn_931_34() Duplicate
SETUP message(?) for Channel 1:21 ~ 1:21 in state DOWN [ignoring]

Befor restart I saw such a line for *each* TDM channel and no one was
able to dial out. mod_openzap handled around 40 outgoing calls until
last restart .

Since last restart FS runs good for 2 hours now without any duplicate
SETUP in log ...

Has anybody similar problems?


regards
Helmut

I think we have some trouble surviving issues.
So when everything is ok we do fine but if something goes wrong we don't recover.
We are still missing state timers in the q931.

maybe you can use your new pcap thing to see what goes wrong =D

Hello Anthony,


yes that's what I'm doing ... beneath some code changes in openzap
... So I found a real timestamp in pcap is quite usefull if you have
more than one call at a time ... I added that function today. It uses
"libapr-1" functions. Unfortunately I introduced a dependency to
libs/apr to openzap by that. If it delivers micro seconds, maybe it's
better to use zap_time_now(). Have to check that tomorrow.

I agree there are some problems in maintaining channel states correctly.
Once a day I have to restart FS. I get "TOMANYCALLS" errors, no matching
channels on RELEASE, SETUP duplicates and "oz dump 1" shows more and
more channels with states other than DOWN, even, when no current calls
are there. I did some timebased changes in ozmod_isdn SETUP handling
and hope it helps out until state timers a available. If it works I
would like to upload it to trunk, if you allow.

regards
helmut

We can not add apr dependency in openzap, we should use the native
openzap calls instead. If there is anything you NEED that you don't
have, please let me know and we will try to add replacement functions.

Hi Mike,

I would like to have a function which gives current time in sec, usec
since unix epoch. It's only for pcap timestamp. I found a zap_time_now()
somewhere in openzap maybe it helps ...

regards
helmut
