Hi Paul,
I would actually not tend to say "the only solution" -- for PSTN
accounting accuracy, which mostly matters, use of gateways with
session-timer work well. Other cases to cut a call do not appear
compelling to me -- in the end, phones will detect the conditions
and hang up.
B2BUAs have also side-effect, at least weaker scalability.

ser is 100% unaware of call status. Ser only maintains transaction
state, not call state.
If your SIP UAs support the Session-Expires header then they will
automatically send re-INIVITES which will disconnect the call and send
a BYE message to SER in the event of a failure.
Regards,
Paul
