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

[Rich Adamson]

Or, just do...
exten => 18661234567,1,Goto(800-in)
exten => 8661234567,1,Goto(800-in)

It's kind of tough to truly understand what you are trying to accomplish
(or ask for). Apparently you've got something more in mind that words 
are making it through the list. Reading between the lines, it would 
appear from the 800-in that calls are coming in from some external 
source, and you trying to do something with them. Can you be a little 
more explicit.
