The answer is Yes. The dialog is established at both UA(s) and anyone can send a BYE.
Please refer to section 3.1.2 http://www.ietf.org/internet-drafts/draft-ietf-sipping-race-examples-01. txt - Nasir Date: Wed, 30 May 2007 21:13:55 +0530 From: "P Raj" <[EMAIL PROTECTED]> Subject: [Sip-implementors] BYE after CANCEL & 200 OK To: sip-implementors@cs.columbia.edu Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi I just wanted to know, if BYE can be sent after 200 OK for a Cancel is sent at UAC.
