[Freeswitch-users] failover based on initial INVITE timeout

[Mathieu Rene]

Hi,

originate_timeout does exactly what it is supposed to do, cancel the  
new call if originate doesnt return within X seconds.
In my opinion, I would keep state wether the gateway is alive or not,  
and have a reasonable t1x64 timeout value (5000 should be enough).
This way it'll only timeout the first time the call is attempted.
