[asterisk-users] Blacklist callers from file

[Tim S]

I'm a home user (not business), but I implemented a blacklist function too
after a harassing call to my wife.

Using the Asterisk DB functions, I have a caller ID look-up function before
my IVR-tree starts, a simple if then.  Lookup caller ID in blocked-caller
DB, if found then I kick them to a short dialplan the plays a message
telling them they've been blocked, then lets them record an "appeal"
message.  If a user put someone in the Blocked DB, by accident, I'd want to
have a way for someone to report it to me via phone.

To add a number to the Blocked DB, the caller internal user is allowed a
hot-key on the phone to block the caller in-call, or with screening they
are given an option in the prompt.  When a new number is added to the
Blocked DB, the call recording for the session is retained to be able to
remember why it was blocked.  The Blocked DB will automatically unblock an
entry after a year, to account for number changes, but the entry can be
extended before it expires via an email response.

I did a similar thing for Telemarketers, the phone numbers also
automatically unblock, but only after a month, as most of the worst
offenders I've come across don't stay with a phone number longer than a few
weeks to avoid enforcement by the FTC.  For that I also have a hot key on
the phones for "Telemarketer Goodbye", which adds to the DB while playing a
"Remove me from your list and stop bothering me" message.  This gives my
users a bit of power as they don't have to be polite, or think of an
evasion to the sales person, they just need to push a button and hang up
the phone when they realize is a sales call.

I didn't want to publish code for this since it's a bit long winded, but it
should give you some ideas of things you want to consider.

Best,

-Tim
