Hello,
I have a problem: When someone begins a call from PSTN to my voip
network, the session interrupts after 30 secconds. The UA don't receive
the ACK message(6)[the ACK doesn't arrive].The scheme below indicate this
situation.
P.S. This situation happens just with one type of equipment: atcom
AG468; with other equipment (atcom AT320ED, audiocodes, atcom AG168)
all works fine.
Very strange.
Thunks.

A "ngrep -W byline port 5060" dump would help more ...

Looks like your GW is not doing a good job in record-routing OR your
openser is not doing it right.
I only suppose than because:
- you have two different IP's for the openser\
- PRACK and ACK seem to be stuck in openser, and they do not reach your
UA in the internal network
Indeed, the network dump would be of much help.

Cristian

Hello,
Thanks to All!
The problem was in routing stuff; I have two different IP's for
openser.

New subject: [QUAR] [Users] interrupts after 30 secconds
Ion,
As you noted the problem here is the missing ACK.
Why the ACK is not being forwarded is impossible to tell without looking at
the actual signaling.
Compare the ACK that is failing to proxy to an ACK that works correctly,
look for differences in RURI or Route headers. My guess would be your UA is
not honoring record-route headers or similarly misbehaves.
Tearing down a call due to a missing ACK is normal behavior.
Hope this helps,

New subject: [QUAR] [Users] interrupts after 30 secconds
Hi,
there were some fixes regarding ACK matching in case of spiralling (not
sure it is your case) - please update from CVS and if the problem
persists, as Klaus suggested, posting a net trace will be the most relevant.
regards,
bogdan
