There are a few specific troubled people we do not wish to take calls from.
Our adult black sheep son, I'm very sorry to say.
If he starts calling every minute to harass with a constantly ringing phone, we need a way to cut him off.
Yes, we know he will use another phone, so we need to be able to block multi-phones, adding one at a time. (The Anonymous Call Blocking is there if we need that route, too, thought with GV that has additional consequences).
We would like an ability to block such callers, based on their CID (Caller ID).
Possibly with a standard recording of 'This subscriber does not (currently?) take calls from your number.'
To potentially something individually and customized by the user, 'Dude, we can't deal with you. Please do not call'.
For super extra credit, offer a timeout sort of option.
No calls accepted for the next hour, 6 hours, day, ...
And / or, calls not accepted until June 1 at 12:00 noon.
TYVMIA for considering the request
