[Asterisk-Users] Extentions Variable Dialing QUESTION.

[David Uzzell]

I have this exten code to dial out to a specific group of numbers.

exten => _10XXXXXXXXX,1,Dial(IAX2/user:pass at user/${EXTEN:1})


I want to be able to have one line to handle generic calling so we could 
dial say 10XXXX or 10XXXXXXXXX or 10XXXXXXXXXXXXXXX or something in between.

Does any one know what the exten line would be to be that generic or 
point me to something that would explain it?

Thanks

David
