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

[Benjamin Lawetz]

Or you can treat everything as a 10 digit number retaining in a variable
whether the user dialed one or not

exten => _1NXXNXXXXXX,1,SetVar(ONPRESSED=TRUE)   *** skip this step if you
don't care whether the one was pressed in any of your dialplans
exten => _1NXXNXXXXXX,2,Goto(${CONTEXT},${EXTEN:1},1)
exten => 8661234567,1,Goto(800-in)

Can be your thing or not, depending on what you're using it for.

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.
