Receiving fax calls from this number on a voice line.

The calls appear to be generating from a fax machine. It robot dials every 5 minutes which is extremely annoying being in a healthcare environment. I have only one line appearance of the telephone number that is being dialed. I am planning to add another line to my telephone set which should allow me to forward the call to my fax to determine the nature of the fax.

Fax calls on cell phone at 1am .. Extremely annoying!!

Above # has been calling my cell repeatedly for 2 days now. When I answer is sounds like a fax line. I called the 3 back and no answer. Very annoying!!!
