[SIPForum-discussion] BYE during setup phase

[Abhishek Mishra]

Hi Santosh,

I think Anshupriya's question is quite valid.

As per RFC 3261, Section 15
http://tools.ietf.org/html/rfc3261#section-15

   The caller's UA MAY send a BYE for either
   confirmed or early dialogs, and the callee's UA MAY send a BYE on
   confirmed dialogs, but MUST NOT send a BYE on early dialogs.

In this case, since the early dialog is already established, caller MAY
send a BYE to terminate the early dialog.

Question is what should be the response to BYE? I think the callee
would send a "200 OK" of the BYE and some 4XX for the INVITE transaction.

If any one has seen some implementation using BYE to terminate the 
early dialog then please share your views.

Kind Regards,
-Abhishek
