Repeated unwanted calls.

I didn't answer, they left no message. However clearly this is a scammer (aka telemarketer) as they've called more than once, and there is no legitimate reason anyone with this number would be calling me.

Same thing, Waits for me to say hello then hangs up

Keeps calling - answered once as it looked local - warranty nonsense.  I think they spoof the phone numbers to make them look local as I get same calls on cell with Massachusetts area codes as that is where my cell is from.
