Hi!
I noticed a "phenomenon" that I don't understand:
I make accounting with ser. If all works fine, ser puts into the database:
sip_method: ACK
i_uri: sip:0182011542614xxxxxx@xxx.xxx.xxx.xxx:5060 (xxx.xxx.xxx.xxx = IP
of PSTN-Gateway)
... and after the call, the BYE message reaches my server.
But sometimes, the ACK is logged in the database like this (in the most cases form users
"far away"):
sip_method: ACK
i_uri: sip:0182011542614xxxxxx@my-ip:5060
In this case, the BYE message doesn't reach my server.
Does anybody know what could be the reason and why ser logs the ACK from himself?
Many thanks!

Waht is "my-IP"? IP of caller or callee or SIP proxy?
The URI in the ACK is typically the URI in the Contact header of the 200
Ok message. Thus, the URI in ACK depends on call direction, and wheter
the caller is a strict router (old SIP RFC) or loose router (RFC3261).

my-IP is the IP of the SIP Proxy. I made an ngrep and I noticed that the URI
of the ACK is the URI in the contact. The call was from client to
PSTN-Gateway.
I rebooted the router of the client and all works fine now. Very interesting
what you said about the RFC... I will check it. Thanks!!
