Thanks for the Info. Now that I know it's junk faxes, I used Verizon FIOS to block their calls (Digital Voice -> Calling Features -> Incoming Call Block -> Call rejection from a specific number). Now when they call, our phone never rings. They get a message that tells them we're not accepting their call.I'm sure it useless since a fax don't understand voice, but at least my phone doesn't ring.
I keep getting calls from 570-820-2560 constantly day and night. Unable to block this call. When I looked up the number online, it said that it was serviced by Verizon in Wilkes Barre, Pennsylvania.
