It was lifeblood confirming an appt I had to donate blood. I didn't answer but they left a message while I was here checking out the number. Turns out it was not spam this time
I was having the same issue with this number calling over and over and it sounded like it was trying to send a fax on my business phone line. I found this number on another forum: (732) 389-3900 -- I called and spoke with a LIVE person and he claims he just blocked the lines and he was really nice even though I was really pissed off. Good luck everyone!!
