H Anthony,

I have same problem on each 7th outgoing call. Then a sort of timeout
occurs. During that time, no incomming call is possible.

regards
helmut

Hello again,

hm the bug OPENZAP-18 is not really the same problem as I have. OZ-18 is
about network congestion while mine is about a pri blocking timeout on
every 7th outgoing call.
So, shall I open a seperate bug on jira?

regards
helmut

Yes please. Also, if you can attach some debug information, preferably
reproducing the symptoms with the full debug turned on (F and attach
it as a file that would assist with the research.

It looks like the other side is not responding at all to the setup message so the span is locked waiting to see which channel should be assigned. There is a mutex here stopping the span from using any more channels until it gets a reply to that setup message.

We could either lower the 60 second timeout to a smaller val, unlock the mutex before we make the call (possible race condition) or figure out why you are getting no reply at all from your setup message.

Hi Anthony,

yes I agree, but hey, the other side is a matured EWSD unlikely that
there is an issue left on protocol level after 30 years. I check that
tomorrow.

yes I doubt your EWSD is doing anything wrong, but the communication channel must be interrupted somehow to never get any replies so yes we can try to figure out what has gone wrong in the communication layer.

Hi,

I updated the jira bug. I did a Q931/Q921 trace. Currently there is no
direct hint, that FS is doing something wrong. NT side is just not
anwering the SETUP of FS, buuut, I was asked if FS is able to allow NT
side the channel management, so NT says what channel is to use instead
of FS.


Can FS do this? If so, how can I configure that?

Analyzing the trace throws a new bug: Sometimes our EWSD finds a
checksum errors in FS's RR messages.

more here: http://jira.freeswitch.org/browse/OPENZAP-40


If one of FS board wants the whole decoded trace just raise your hand.

regards
Helmut

Hi Anthony,

thx, but that doesn't work very good. Outgoing calls ring only once and
then this error rises in console:

Helmut,

Can you turn on full debug and capture the output? It's a lot so put
it in a pastebin.
