The re-INVITEs definitely work.  I run some setups with
Jasomi inline (a commercial inline b2bua).  I configure them to
reINVITE, works like a charm.  If the reINVITE isn't answered (in either
direction) the Jasomi sends BYEs in both directions.  I believe other
commercial gear works that way.

Also, I believe Session-Timers are supported by Cisco gateways, but
I don't have experience with those.
