-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Daniel Hsueh Sent: Tuesday, January 17, 2006 3:46 AM To: [email protected] Subject: [Sip-implementors] Q: can a call stateful proxy send a BYE to terminate forked INVITEs that already have 200 responses? Hello, (Apologies -- I expect this question to have been discussed already, but I'm unable to locate a discussion in the archives.) RFC3261 explicitly states that a proxy may initiate CANCELs along forked INVITE destinations when a first response comes back. I cannot locate anything saying that a BYE cannot be sent. My reading of RFC4028 Sect. 8.3 suggests that proxies MUST NOT send BYE messages. [ABN] this does mean, the proxy should not generate the BYE or any other message, with an exception, and it can generate CANCEL on reception of 2xx or 6xx to INV. Hence it's been mentioned as MUST not send BYE (implicitly mean should not trigger BYE from itself). If it receives the BYE from UAC/UAS then it has to forward / fork depending on the prevailing conditions. Is there a specific section of an RFC/draft that covers this exact question, or does it need to be derived from other RFC requirements?
