Thanks, Joshua.

We want to check if a peer is responsive every few seconds, because it's a
person-to-bot call and we want to respond gracefully if the bot fails.

I tried adding
to the config of the peer in sip.conf, but this causes hangup during the
person's turn.

Then I looked into session timers, and found that
says the shortest period supported for such checks is 90 seconds, which is
much too long for us.

Is there another option? Would it allow calling a script or playing a
prompt on the way to hanging up?
