I am sorry, maybe I do not understand enough about SIP and proxies.
Wouldn't it be possible to fake re-invites? Tell each phone that it
gets a reinvite coming from the other phone, and basically redirecting
the sound stream to an rtpproxy for example? or a codec translator?

I'd like to switch from g711 to g729 when the link gets overloaded
for example. Or record the phonecall.

I am trying to learn more about SIP. Aren't reinvites within
a dialog common?

Maybe I could make changes to openser to enable this?
