I also want to make sure I include relevant portions of the openser.cfg

                        # if found,lookup aliases and  forward there...
                        lookup("aliases");

looks like a dialog matching problem. for further inspection complete SIP dums would be necessary:
ngrep port 5060

I find that I am having the same error, although with me it only happens when the sip client is natted and the bye comes from the pstn end. Sample tethereal capture below. I can only assume this has something to do with the nat module which I am currently not using yet but plan to try again to implement today. 48.022862 216.120.255.29 -> 8.11.1.7 SIP/SDP Request: INVITE sip: [EMAIL PROTECTED], with session description 48.026850 8.11.1.7 -> 216.120.255.29 SIP Status: 100 trying -- your call is important to us 48.027059 8.11.1.7 -> oursippproxy.net SIP/SDP Request: INVITE sip:[EMAIL PROTECTED], with session description

Hi all,
I would like to know why does my BYE method are always replied with a 'Call Leg/Transaction does not exist' . How do they compare whether the transaction in the BYE method exist or not ? ( tag? ftag ? ) Are there any thing in the config that might cause this kind of problem ? Just want to highlight that all the calls are made in a good condition, everything except when the call is ending.

Please let me know if you dont understand.
 Regards,
Sam
