[asterisk-users] extensions.conf pattern match info

[Eric "ManxPower" Wieling]

The following two wiki pages explain it much better than I could.

http://www.voip-info.org/wiki/view/Asterisk+Dialplan+Patterns
http://www.voip-info.org/wiki/index.php?page=Asterisk+Extension+Matching

I'm not a fan of using the Wiki as a reference, but there really isn't 
any info like this in the docs that come with Asterisk.
