As far as I know and understand it seems that the R-URI of the BYE mesg (1st line) which GW sends to SER is wrong.
I expected to see : BYE sip:user@SIP_Phone_IP_Address SIP/2.0
or the problem is that the 'Route:' header is missing from the BYE mesg so it's not loose_routed.
Do you Record_Route the original INVITE ?

Hello, The call signalling exchange is a good start but it's not enough.
What some people here asked you is a capture of the SIP BYE mesg which GW sends to SER.
Kostas, Thank you for suggestion. I've already posted SIP BYE message found with ngrep :-D. However here is: U 2007/05/15 14:26:15.072602 10.28.52.105:5060 -> 10.28.19.202:5060 BYE sip:10.28.19.202 SIP/2.0. To: sip:06605XXXXX@10.28.19.202;tag=23d09968cf17c929.
