Hi Peter,

Thank you for your response.

On Friday, I received only one call from the "parasite". I'll wait and
see what happens first. Maybe it will stop?

Yes there are such devices. I've seen them in the past, basically
require the caller to press a number to get past the magic box. Since
automated call machines can't press the number, they don't get connected!

"Please press 5 to complete this call..."

Caller presses 5. And your phone rings.
