Who called from 7204520054

called today...left message and it was just beeping for 51 seconds then nothing....like a fax tone but more like the ones you hear just before a collection company or telemarketer pick up the line...

our main company # ( the receptionist) gets calls from this number several times a week, whe she answers, all she hears is a FAX tone

my voice mail on my cell phone stated there was a fax waiting for me from this number...what is that about?

This number called our home office line last night between 12:30 AM and 2 AM non-stop!  Now that I'm reading these posts stating that this is a FAX line it makes sense that the number just keeps redialing,

Call me almost every weekday morning. Very annoying and should be stopped
