In this case the ? modifies the *, so there's .* (greedy) and .*? (not greedy)<br><br>You want your .* to match as little as possible instead of as much as possible. If you use .* instead of .*? then your $2 would contain both the ndpi info but also it would have ";rn=18005551212" b/c the .* would grab all that stuff. The .*? would only grab up to the ";rn".<br>
<br>Just adding that info for posterity's sake. :)<br><br>-MC<br><br><div class="gmail_quote">On Mon, Jan 7, 2013 at 5:05 PM, Ken Rice <span dir="ltr"><<a href="mailto:krice@freeswitch.org" target="_blank">krice@freeswitch.org</a>></span> wrote:<br>

Maybe this would be more effective:<br>
^(?:+1|1)?([2-9]\d{2}[2-9]\d{6});ndpi=(.*?);rn=([2-9]\d{2}[2-9]\d{6})$<br>
