Who called from 4153290365

A guy selling home alarm system. He has been calling for years with various phone numbers (including different area code).

Home alarm telemarketer- why would I buy from a blind call?

I continue to receives calls from this number: 415 329 0365

No message left on voicemail. When I call them back minutes after their call i hear an obviously fake "This number has been disconnected" message.

I've got a call yesterday from 415-329-0365 and another call from the same number today.  I didn't pick up the call yesterday and they did not leave a message.  I picked up the call today and they hung up.
