Well, it's the simplest approach conceptually but i get your point:
it's not plug and play if compared to packet classification. As said
most depends on the scenario: if it's "walled" and you are in full
control of the codec and its parameters then it's easier; otherwise
it gets tricky.

No. And the issue with the kernel-based packet classification engine
is that it remains external and has to be queried somehow - can't be
just embedded.

Agree.

Is also the RTP passing in all cases (ie. off-net and on-net calls)
through the Openser/Asterisk proxy/registrar? Such a case would ease
guessing of RTP streams.
