Hi Ravi,

I am not sure what is need of the authentication for a BYE request. I think
there is no need to authenticate the BYE request becoz BYE is coming with in
the Dialog. Also it have the same branch and Call ID of the Invite so I
think there is no need to authenticate the BYE.

In your case if the authentication fails then check the Binding time is of
that UA. Suppose if that exceeds then terminate the session.

cheers..
Balaji
