[Asterisk-Users] Interesting Dial-Plan Question

[Matt]

Ok here is what we did.. all in one context:

exten => _NXXXXXX,1,NoOp(Customer Area Code Is: ${CALLERIDNUM:0:3})
exten => _NXXXXXX,2,Goto(${CALLERIDNUM:0:3}${EXTEN},1)
exten => _1NXXXXXXXXX,1,NoOp(Chopping One Off Number: ${EXTEN:1:10})
exten => _1NXXXXXXXXX,2,Goto(${EXTEN:1:10},1)

Had to fix Eric's code a bit... CALLERIDNUM::0:3 didn't work :P  But
that works great!  Call lengths to US calls are now standardized :) 
Before it showed up however you dialed it hehe.
