You can't make 1. without a B2BUA. Who else will disrupt the call in case of zero balance?
Perhaps I am missing something, but why not either a) The media gateway, or b) Assuming you have a stateful proxy, the proxy server (with suitable hackery) - how would the UA/proxy upstream/downstream from the proxy *know* if the proxy really received a BYE, or just faked one up? So if you send one BYE in each direction, you get two ACK packets produced which would perhaps confuse their final recipient, except the proxy server will eat them.
