calls all hours usually will not leave a message and if answered will be silence and then hangs up. ( this is a "spoofed caller ID")

Got a call from 253-320-0092 was a Jamaican guy trying to fraud mom out of $$. Same guy calls from 876 and others, obviously a "spoofed caller ID"

Silence or background noise as in a bar, or open room with telephone solicitors.

Called mulitple times from 253-203-0092 with a recorded voice asking for first name of someone who doesn't live here. I want it to stop.  Who is this company?

a "spoofed Caller ID"  Call *57 to trace back the next time they call (must be done after they hang up, Then report to the FCC.)
