Who called from 3608419174

I've had up to 6 calls a day from this number.  So far today I've had 2, neither answered because I don't know who/what/when/where/how the number is

3 calls in the last 2 days - glad I have a smart phone so I can reject the call before it even rings.

360 is a Western Washington (state) area code

Didn't answer. No message

I've had 11 calls in a little over a week...finally answered the last one and he asked if I wanted a free home security system, an $800 value.  After I told him a couple times I wasn't interested he hung up on me just as I was going to tell him to take me off the list.  Tried to call the number back, it rang once and then sounded like maybe it had been answered by niobody was there.
