Who called from 7604813173

Same here, calls every day or two and it hangs up after answering.  When you call the number back it doesn't go through.

Received two calls from this number in the past two days: Both times the caller hung up and left no message. Based on the area code (760), I suspect it's a solar spammer as almost every 760 number caller us has been a solar contractor nuisance call.

My story with this number is pretty much the same.  I didn't answer and when I called a while later all I got was a busy signal.

This is a market company of some kind. When you call the number back it is unavailable. I put them on my block list.

Solar BS. Number blocked.
