[Freeswitch-users] Excluding phonenumbers from existing matches?

[David Ponzone]

Thomas,

Sure, you can't find a regexp to match a list of random numbers, as the whole point of a regexp is to match numbers which have some common part(s).
And also, the RegExp implementation in FreeSWITCH is not as complete as in the lib (named placeholders for example would be nice).

I think in your situation, you should go for the simplest/easiest.
Just add a condition before the one with your regexp, with break on-true:

<condition field="caller_id_number" expression="^03066664|0800330\d$" break="on-true">
 <action application="hangup"/>
</condition>
<condition field="caller_id_number" expression="^your regexp from hell$">
etc...

If you need to manage this blacklist from a DB, I would do something different:

<condition field="caller_id_number" expression="^your regexp from hell$">
 <action application="lua" data="validate-callerid.lua"/>
 etc....
</condition>

validate-callerid.lua is a rather easy to write LUA script, where you check the caller_id_number variable against your DB (one SQL SELECT) and if it matches, you can hangup or redirect the call to a message saying "Due to the past activity from your number, your calls to our system have been filtered".
If it doesn't match, you do nothing, and the dialplan will go to the next action, where your "bridge" is, probably.

You may rather call this LUA from a previous extension, quite early in the dialplan, if you want to drop the call ASAP and globally for all your platform.
