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

[Sean Kennedy]

Rich,

/It's kind of tough to truly understand what you are trying to accomplish

/Ack, sorry!  It's hard to post to the list on a saturday when my 2year 
old is wanting to play with the keyboard as well.  Best I can do is half 
a mind, most of the time that's enough. 

Not always, however.  :)

/(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
/
I have an 800 number from teliax.  When my "local" users dial it, they 
will dial 1866... instead of the 866 I have in my dial plan.  I do not 
want the call to use one of my external sources to terminate the call ( 
in essence, dialing out via voicepulse, and recieving the call via 
teliax ).  I know I can do two seperate exten patterns, but I was hoping 
for a single pattern.  To that end, I was wondering if there was a way 
of saying "Match this 0 or 1 times", something I'm used to in perl and 
the like.

If there isn't, there isn't.  Won't kill me to add the second exten match.
