Who called from 7206067075

I continue to get calls from this number and it sounds like a fax is trying to come through.. They call at least twice a day... getting really annoying.

Got a call at 6:24 AM from this number..on my cell phone. Who does that? Did not answer in hopes that I get dropped from the call list.
