[Asterisk-Users] pbx spool question

[Steven Poelmans]

Hello all,

I have a question about the pbx spool and extensions.
After I put a "sample.call" in /var/spool/asterisk/outgoing,
Asterisk calls out and jumps to context ringback.

[ringback]
exten => s,1,ResponseTimeout(5)
exten => s,2,DigitTimeout(5)
exten => s,4,SetVar some variables
exten => s,5,Background(menu/menua) ; enter a key from 1 to 5
exten => _[1-5],1,AGI(evaluation.agi)
exten => _[1-5],2,Hangup

Everything goes fine, except for the _[1-5] extensions. Asterisk doesnt
respond when I enter a key. I also tried 
exten => 1,1,...
Isn't this possible with pbx spool?

Thanks in advance,
Steven
