hi,
if after you have got a final response of 200 OK and you want to
terminate the call by sending a BYE instead of sending an ACK. This is
stated in the rfc2543 : "If the caller no longer wants to participate in the
call, it
sends a BYE request instead of an ACK." in section 1.4.4. Also the bis-03
says that u should not send a BYE before getting a final response. It
doesnot say that u must send an ACK first and then terminate the call using
a BYE.
hope this helps
thanks and regards,
gautham
