RTPProxy has been working nicely for me thus far but I've introduced a
new Fax Server which doesn't play nicely with RTPProxy for some reason
:(.

You mean 'Now all corner cases'?  So I would use engage_media_proxy()
and also need to implement the dialog module?

Does MediaProxy require 2 servers.  One for OpenSIPS and one for the
relay?  Dispatcher can run on the same box as OpenSIPS?  Or can it all
go on 1 server.

Any particular reasons against using RTPProxy?
