Hello Markus, Once you have a early dialog and a confirmed dialog .. I think you should be sending a CANCEL from the UAC side for the early dialog ... The proxy server will respond back with a 200 OK and clear any pending client transaction (if any are left ) by canceling them as well. See section 16.10 in 3261 on how the proxy will handle the CANCEL request from the UAC on the early dialog. Regards , Sayan

Do I understand it right, that it is allowed to send a BYE for an early dialog from the UAC side? Imagine following scenario: UAS sends an INVITE to a proxy. The proxy forks the INVITE and two provisional response with different to tags are coming back. One UAS sends a 200 OK and the proxy cancels successfuly the INVITE request to the other UAS. The UAC has now a confirmed dialog and an early dialog. MAY the UAC send a BYE the the successful canceled UAS? When can the UAC clean up the early dialog? Thank you in advance. Markus P.S.: Sorry, I forgot the first line. :( ______________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!
