[Asterisk-Users] extensions and regular expressions ( probably an easy question )

[Daniel Wright]

Sorry I read that wrong.

You could use something like this or just put two lines for each extension

exten => s,1,GotoIf($[$[${EXTEN:0:4} = 1866]?2:3)
exten => s,n,GoTo(wherever1)
exten => s,n,GoToif($[${EXTEN:0:3} = 866]?4:5)
exten => s,n GoTo(Wherever2)
exten => s,n,What-ever-could-come-next

You can also change the jump 2:3/4:5 to the contexts you want to go to. I am fairly new to the dialplan so not sure if this will work exactly like you 
need, but this should give you an idea of where to go from here.

Hope this helps

Dan
