[VoIP] Blocking Individual Calls

[Doug Alderdice]

Hi gang,

What's the Asterisk language for extensions.conf to block calls from a 
particular CID?  I've had someone calling through John Covert's PSTN port 
making a number of calls on my system here over the last 14 hours and 
generally making a nuisance of himself/herself including ringing a 
nonpublished number on my switch a little while ago and hanging up when I 
answered -- and after it got my folks all confused with the particular line 
ringing.  I see from the call logs this person also tried another "live" 
number at 0045 local time last night, but got caught in the "waking hours 
only" routine in Asterisk.  Also this caller appeared to be checking out 
the capacity of my system by calling either the RNA or busy line and then 
attempting another call on the switch at the same time... sorry I have only 
one port from Asterisk to my step switch.

Anyway, I think this person needs to be blocked.  What's the command(s) to 
accomplish this?  And the CID is apparently nonpublished as a reverse 
lookup on Anywho.com doesn't give a result, but the pay-for-information 
sites claim to have a listing.

Many thanks,

Doug.
