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.
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!!!
