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.
|cisco-gateway| | openser | |UA's| X.X.X.X - public ip adress eth0-X.X.X.Y - public IP 172.17.6.0/24 | eth1-172.17.6.2 | | Invite | Invite | 1 |------------------------------->|----------------------------->| | Trying | Trying | 2 |<-------------------------------|<-----------------------------| | Ringing | Ringing | 3 |<-------------------------------|<-----------------------------| | PRACK | | 4 |------------------------------->| | | 200 ok | 200 ok | 5 |<-------------------------------|<-----------------------------| | ACK | | 6 |------------------------------->| | |................................|..............................|30 s | Bye | Bye | 7 |<-------------------------------|<-----------------------------| | 200 OK | | |------------------------------->| | | | |
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.

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

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,
tr

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
