Same home security system scam as calls from dozens of other numbers.  Oh well - at least there's less than 10 billion phone numbers for them to go through before they've used them all up.  I pity anyone who inherits one of their besmirched numbers after they're done abusing it - nothing like already being blacklisted by millions of people on a phone number you were just assigned.

Just got a call from this number, answered with hello but no one said anything back.

Calls every darned day.  Home security scam and they don't take no for an answer nor do they bother honoring the Do Not Call warning.   The next time they will get a bull horn NO treatment from me.

I never ever ever answer a call from a number that does not give me the name of the caller.  Period.  Add to that an out of state area code and they also get added immediately to my blocked list if they don't leave a voice mail.  By the way my voice mails says I wont answer the phone on unknown calls so if you really want to talk to me, be legit and leave a voice mail. Funny. They never do.  Oh well. These aren't even an inconvenience any more.   Call all you want.

The 0nly way to stop all these calls is to opt out sharing your info with the 3 big credit agency's.
