Sending an empty INVITE has the appeal of working with either side (no
matter with which you begin). With the other, you might have to remember
which side initiated the last INVITE or UPDATE transaction, and send the
last positive SDP answer to this side as a re-INVITE. Or am I missing
something?
However, it might happen that the one of the ends does not support
receiving empty INVITEs... (less probable today).

clean? I am not so sure any more, trying to hack
something together to
see where this gets. Is there a clean and simple method to do re-invite
from the b2bua, which catches all the possibilities (changed session
etc)?
e.g., one possibility, reinvite with last SDP from the other side
From my understanding of SSTs, this is the correct approach (last
known SDP). This has the advantage of not breaking the changes of
real re-INVITEs that actually happened.
