Note: "send BYE instead of sending an ACK for a final response". This is
^^^^^^^^^^^^^^^^^^^^^^^^^
what I was pointing out as being in error. You MUST send an ACK. The ori-
ginal poster wanted to know (I believe) if it was okay to send a BYE to a
call leg a UAC does not want to maintain, or if an ACK was needed before
the BYE. Clearly, an ACK is needed before the UAC can issue a BYE.
