That's really weird, why are not ACKing the first 200 OK? Is this on purpose?

Every 200 OK will request port from rtpproxy, but The call is byed. 
I don't want to request port any more, so to drop it.

1. Why would you want to drop it?

‎2. Any reply has a CSeq value matching the request to which it corresponds. So, $rm, method, and is_method() in an onreply_route can all be used to test for a BYE.
