[VoIP] Blocking Individual Calls

[Greg Blakely]

Shane's way is the easiest, not needing any gotoif statements.

Something like this should trap 7045791541.

exten => _136635XX/7045791541,1,Congestion
exten => _136635XX,1,Dial(ZAP/1/${EXTEN:6})
exten => _136635XX,n,Hangup

This sends anything to 1-366-35XX to your zaptel device, unless it comes
from 7045791541.  In that case, it goes to Congestion, i.e., all
circuits busy.

I use it at home for telemarketers...

exten => s/2182062192,1,Goto(spam-intercept,s,1)
exten => s/3202594099,1,Goto(spam-intercept,s,1)
exten => s/5102738910,1,Goto(spam-intercept,s,1)
exten => s/7012394294,1,Goto(spam-intercept,s,1)
exten => s/9529083215,1,Goto(spam-intercept,s,1)
exten => s/9529083216,1,Goto(spam-intercept,s,1)
exten => s/9529083218,1,Goto(spam-intercept,s,1)
exten => s/9529083219,1,Goto(spam-intercept,s,1)
exten => s/9529083220,1,Goto(spam-intercept,s,1)
exten => s/9529083221,1,Goto(spam-intercept,s,1)
exten => s/9529450192,1,Goto(spam-intercept,s,1)
;
exten => s,1,NoOp(Entering dr1 context)
exten => s,2,Answer()
And so forth.

It blocks calls from those 11 numbers, sending them to a
'spam-intercept' context, which tells the caller that the number they
have reached has been disconnected.  (I lie to telemarketers).
