Hi All, I have a doubt regarding Reason Header in BYE request.
We can have the different Reason Header in BYE request depending on the call state. Some of the examples are given below: Reason: SIP ;cause=600 ;text="Busy Everywhere" Reason: SIP ;cause=580 ;text="Precondition Failure" Reason: SIP ;cause=200 ;text="Call Completed Elsewhere" My doubt is - what should be the Reason Header if BYE is sent after server transaction times out waiting for ACK? 13.3.1.4 The INVITE is Accepted If the server retransmits the 2xx response for 64*T1 seconds without receiving an ACK, the dialog is confirmed, but the session SHOULD be terminated. This is accomplished with a BYE, as described in Section 15. 15 Terminating a Session However, the callee's UA MUST NOT send a BYE on a confirmed dialog until it has received an ACK for its 2xx response or until the server transaction times out. In this case, can we have something like the following in BYE request? - Reason: SIP ;cause=200 ;text="Call Completed Normally" Would this be wrong as it is not a normal call termination?
