[Asterisk-Users] Fall back dialing

[Chris Mason (Lists)]

We have ServerA that connects to ServerB to dial long distance via an IAX2
trunk. I have setup an international dialing plan so that there is a backup
route via pstn if the IAX channel is down.

exten => _1NXXNXXXXXX,1,Dial,IAX2/${SERVERB}/${EXTEN},60)
exten => _1NXXNXXXXXX,2,Dial(Zap/g2/${EXTEN},70)
exten => _1NXXNXXXXXX,3,Macro(fastbusy)
exten => _1NXXNXXXXXX,4,hangup
exten => _1NXXNXXXXXX,102,Dial(Zap/g2/${EXTEN},70)
exten => _1NXXNXXXXXX,103,Macro(fastbusy)
exten => _1NXXNXXXXXX,104,hangup


Would it be better to use

exten => _1NXXNXXXXXX,102,GotoIf($[${DIALSTATUS} = CHANUNAVAIL]?i,1:103)


Any other improvments? We want to make is transparent to the users.
