They don't *just* spoof your local area .. I once got a

that's the easiest of all to block with no risk whatsoever.

Not if you have an alarm system that calls you...

why is the alarm system calling you using your own caller id and not
that of the alarm company? and if you're home, why does it need to call
you at all?

No need for an alarm company - I think they're useless. It calls me by
landline & a cellular connection, so cutting every wire going to my
house won't foil the alarm system.

that doesn't answer the question, which is why it's calling you with
spoofed caller id, that being your own number and not theirs, and if
it's both landline & cell, then at least one of them should be
different.

I have cameras inside, so I can
look around the place, and then call the police if someone is actually
in here, which has never happened. *Everything* has battery backups,
and if someone cuts my power, I know within about 15 seconds. I spent
a lot of time on this...

And I'm not even in a high crime area.
