[Freeswitch-users] continue_on_fail for condition only where 100 not received?

[David Ponzone]

I think the original question was: is there a way to failover if the remote gateway does not send back anything (no 1XX, no 2XX), with a configurable INVITE timeout (5 seconds would probably be better than 60).

To answer to Mike:
I think we should consider the possibility that the remote gateway answers correctly to SIP OPTIONS, but only fails to respond to INVITEs. I saw weirder things :)
