Who called from 6183148085

Spam call,  keeps calling my fax line that is unlisted.

Got a call from this number did not answer didn't know the number no voicemail at all.

Same here. Just called about an hour ago. Didn't answer. I've never received a call from that area code so I assumed it was spam

Same - got a call from the IL number (at 7:16am PST which was annoying - but I have an east coast #). No message. Didn't call back. Likely spam, considering all the calls seemed to have happened in the last couple of days.

Same thing, I didn't answer, they didn't leave a message. It's been flagged as a not safe number on various websites.
