[Asterisk-Users] Multiple gateways for same dial pattern

[Adi Linden]

I can do the dial command like this to give me a 20 second timeout

    exten => _9737XXXX,1,Dial(SIP/${EXTEN:1}@172.17.99.5,20)

But this also means that after 20 seconds of ringing it goes on the next
dialpeer. I would like to be able to set the timeout Asterisk wait to
establish a connection, any connection, with the gateway to something much
shorter than it is now.

Similar to what you stated, I use VoipJet/NuFone at home. The other day
VoipJet had problems and my calls didn't go through. I took the
opportunity to try configure some sort of failover configuration to
NuFone. Couldn't make it work in an acceptable manner and had to manually
change the dialplan.
