[asterisk-dev] Adding a call preemption feature

[Phil Mickelson]

Jean,

You should know that I wrote something very similar to what you are asking
for.  Slightly different reasons and I use ARI which makes it very easy.
However, the result is the same.  The inbound call gets terminated.

For those of you who don't know why you'd do this here's the situation:  If
you're running a live operator answering service and have a customer who
hasn't and won't pay their bill but still forwards the calls.  Unless you
terminate the call when it comes in then you have operators answering calls
where they have to tell the caller they're not going to get taken care of.
It's much easier to just terminate the call before it's answered.  ARI
makes this very easy.  And, BTW, it get the customer's attention very
quickly.  And, the bill is generally paid!

Everyone has some feature that's important to them.  Just because you don't
understand or see the reason doesn't mean it's not valid.
