[Asterisk-Users] Dial and Congestion

[FaberK]

Hi folks,
very stupid question, how do I setup a Dial with multiple Zap choises?
I've setup this, but maybe is wrong:
------------------------------------------------
exten => _7653.,1,SetCallerID(${CALLERID(number)})
exten => _7653.,2,Dial(Zap/g2/${EXTEN})
exten => _7653.,3,Dial(Zap/g4/${EXTEN})
exten => _7653.,101,Congestion
------------------------------------------------
what I want to do is that as soon as lines are not available on g2, all
others outgoing calls must go to g4.
Should be very easy, but it do not work.
If the configuration is correct, then I must check the PRI.

Thanks again
