Hello list Beside the BYE problem that i post in a past mail, i detected another weird behaivor of SER. When i made a call from a registered endpoint (64.76.148.242) to a PSTN-number through a PSTN-Gateway. The destination devices keep ringing even if i send a CANCEL message. I don't understand why. Here is the debug U 64.76.148.242:5060 -> sersip.mydomain.com:5060 CANCEL sip:005622408196@sersip.mydomain.com SIP/2.0 Via: SIP/2.0/UDP 64.76.148.242:5060;branch=z9hG4bK1f42736da4462 From: <sip:5555832351@sersip.mydomain.com>;tag=1f42736da4 To: <sip:005622408196@sersip.mydomain.com> Call-ID: 1f629d42-2d9e-73aa-826d-0002a400f1e9(a)64.76.148.242 CSeq: 462 CANCEL Date: Wed, 01 Jun 2005 07:22:16 GMT User-Agent: AddPac SIP Gateway Content-Length: 0 Max-Forwards: 70 # U sersip.mydomain.com:5060 -> 64.76.148.242:5060 SIP/2.0 404 Not Found IT!

Can someone help me here,
