Rec'd call.  I picked up & said "Hello?".  There was dead air (i.e. a "silent call").

Altogether I have received 4 calls from this & 2 similar numbers in the past 3 days.

587-887-1871:  Apr 14
587-887-1873:  Apr 16
587-887-1875:  Apr 15, Apr 14

I believe I read in the 800notes comments for one of the other numbers that it's the Progressive Conservative Party calling to do "voter identification".  I cannot corroborate this though.

All they're doing is PIXXING me off when they can't identify themselves in the Caller Name field; I think they blank this out intentionally.

I receive enough nuisance calls as it is.

Same Conservative support getter disguised as a poll. They are also using 587-887-1871 and 587-1875.  Dishonest method from a dishonest party. They seem to use a new number after the last previous one gets enough negative reports

Same thing, also calls from 5878871875

I'm getting the same thing from this series of numbers... dead air.
