Who called from 3122811746

This fax machine also has another number 206-829-4810. They have called repeatedly this morning in a 5 minute span. I faxed back both numbers with a notice that they were faxing a regular phone. For now the calls have stopped.

Calls throughout the day, approximately 20 times, and only beeps as if a fax is trying to come through. It needs to stop.

Also 206-829-4809

Constant fax ringing my office phone all of a sudden today. Never had a problem before, but it has been constant for the last half hour rotating between these 3 numbers and won't stop
