fax number can't stop it

i have received calls from this number multiple times, it sounds like a fax or modem number that is trying to call me, have as well been receiving calls from other numbers with the same area code, all have the been within the past about 4 hrs, over and over
please help make these calls stop

Same thing this morning!!! They called about 10 times between 9 and 10:15 AM....I'm gonna go crazy. I tried to call back at one of these''1-201'' numbers, but nothing!

I'll call my phone company to block any phone number starting by 1-201-!!!

just weird
