We are receiving a new and difficult-to-handle form of phone spam about every other day starting in the last few weeks.
The caller spoofs caller ID to the form of
our area code - our exchange - four random digits.
Even with wild cards, we can't reasonably block everyone in our area code and exchange.
I'm wondering if there is a way to block all numbers in our exchange except for those in a whitelist.
And a second question: what is the message that a blocked anonymous caller hears, if we use that option?
