[Freeswitch-users] Call Screener

[Todd]

What I need it to do is this:  I have apprx. 100,000 numbers from across the
country provided by eTollFree, PacWest, XO, Global Pop, and Vitelity.  In
order to prevent call bomb DoS attacks I need FS to screen the CID of every
incoming call and BlackList or Block any CID's that violate a threshold of
20 call per minute or day even.  I was thinking that limit_hash 

<action application="limit_hash" data="cidlimit ${caller_id_number} 20/60"
/>

Would block any calls from the same CID above 20 in a one minute period.  If
there is a better way to setup FS to examine every incoming call and
BlackList CID's that violate threshold parameters that you could tell me
that would be great.  Thanks!

Just screen calls?  Limit and limit_hash are for tracking how many calls /
how many calls per second.  Use the dialplan if you just want to allow
certain numbers through.

Tell us the functionality you want and we can make recommendations.
