[Freeswitch-users] Dead gateway detection

We've two outbound routes from a FreeSWITCH box, both done purely
on IP - no SIP registration or authentication involved apart from by IP.
We can route calls to one or the other by adding a Route header to outbound
call setups, which works fine. What I can't obviously see how to do is to
failover if one of the gateways disappears. Two options that I've come
- add some code to fail a call if a 100 Trying isn't received within a
after sending the initial INVITE, so that it can be routed to the other
- using an external app to periodically send OPTIONS to each gateway, work
out which are alive, and route calls appropriately.
Have I missed something obvious and straightforward?
