If you are trying to match the dialed digits "*999*11#" then yes, the pattern you suggested below is not appropriate. Just putting special characters inside of [ and ] is not enough to change their meaning. The proper way to handle this is by doing what Covici suggested and use a \ (backslash) in front of the * characters. (The # char is not one of the special characters in PCRE, therefore it does not need a backslash.)<br>
<br>The best pattern for your example is:<br><br>^(\*999\*11#)$<br><br>That would match "*999*11#" and absolutely nothing else. If you need to be flexible on the digits that you match you could do something like this:<br>
<br>^(\*\d\d\d\*\d\d#)$<br>
<br>That would match * plus 3 digits plus * plus 2 digits. Example matches:<br>*123*45#<br>*876*99#<br>*333*33#<br><br>You could even grab the internal digit sequences and put them into $2 and $3:<br><br>^(\*(\d\d\d)\*(\d\d)#)$<br>
<br>Notice what the special vars contain by using this little table:<br><br><font face="courier new,monospace">Dialed: $1: $2: $3:</font><br><span style="font-family:courier new,monospace">*123*45#</span> <span style="font-family:courier new,monospace">*123*45#</span><font face="courier new,monospace"> 123 45</font><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">
*876*99#</span> <span style="font-family:courier new,monospace">*876*99# 876 99</span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace">
*333*33#</span> <span style="font-family:courier new,monospace">*333*33# 333</span><font face="courier new,monospace"> 33</font><br style="font-family:courier new,monospace">
<br>I strongly recommend that you try it out. Put this in your dialplan and try it out:<br><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace"><extension name="tinkering with regexes"></span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace"> <condition field="destination_number" expression="^(\*(\d\d\d)\*(\d\d)#)$"></span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace"> <action application="log" data="INFO \$1 is $1"/></span><br style="font-family:courier new,monospace">
<span style="font-family:courier new,monospace">
<action application="log" data="INFO \$2 is $2"/></span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace">
<action application="log" data="INFO \$3 is $3"/></span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace">
</condition></span><br style="font-family:courier new,monospace"><span style="font-family:courier new,monospace"></extension></span><br style="font-family:courier new,monospace"><br>Try it out - make a bunch of calls and see what happens. Change the regex around and try dialing again. I promise you that once you start writing your own regexes - and occasionally breaking them in the process - you will learn them and use them to your advantage.<br>
