Hi Greg,

that's the fortunate case of having already a B2BUA on the path :). But only for this particular case, I find the usage of a B2BUA a little bit to "heavy"....

Session Timer is actually doing a great job ;)

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.

Thanks for the info guys! It sounds like I need to do a little reading
up on cseq to determine if this will even work, or find a PSTN gateway
provider that supports Session-Timers.

by sending re-INVITEs from the middle of the path you will increase the
cseq number differently on each side...so you will need to synchronize
the cseq value when some in-the-dialog requests are passing through your
proxy....and that's quite complicated....

Would it be possible to fake a REINVITE then check the response to
determine if a call is still in session? Just brainstorming...
