[VoIP] Asterisk Dialplan Question

[Greg Blakely]

True.  And I probably would use something a little more granular, like
using the DIALSTATUS variable.

exten => _1NXXNXXXXXX,1,Dial(IAX2/account at provider1/${EXTEN})
exten => _1NXXNXXXXXX,n,GotoIf($[$[${DIALSTATUS} = "CHANUNAVAIL"] |
$[${DIALSTATUS} = "CONGESTION"] ]?continue)
exten => _1NXXNXXXXXX,n,Hangup
exten => _1NXXNXXXXXX,n(continue),Dial(ZAP/g9/${EXTEN})
exten => _1NXXNXXXXXX,n,GotoIf($[$[${DIALSTATUS} = "CHANUNAVAIL"] |
$[${DIALSTATUS} = "CONGESTION"] ]?next)
exten => _1NXXNXXXXXX,n,Hangup
exten => _1NXXNXXXXXX,n(next),Dial(ZAP/g9/${EXTEN})
exten => _1NXXNXXXXXX,n,Hangup

I haven't tried it on my own system, so there may be errors, but you can
probably see them scroll past on the screen if there are any, and you
can fix them.
