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

[Rushowr]

Definitely should just copy the 18661234567 extension set and then remove
the 1. I do not believe you can use regular expressions (I take it you _do_
mean regex, and not the standard pattern matching)

That's all I got...

Hi Dan,

Thanks for the info, but what I'm after is the ability to match a
digit/character 0 or 1 times at the beginning of the string.  If I'm reading
your example right, it'll match anything starting with 866, which doesn't
work for me.  I am trying to match:

18661234567 and 8661234567

Sean

ps:  The pdf doesn't have a good explaination of this either, although it
occurs to me that this might not be possible with * if I'm having such a
hard time finding it.
