I think this is just a hired call center that businesses hire to place outgoing calls.

For example - I got a call from this number today and it was from Marlboro telling me an event that I was scheduled to go to has been cancelled.  That was pretty much it.

Yup, Verizon just called me at 11:15. The phone rang three times, and stopped.

I thought Verizon stopped work early. At least, that's what the Comcast commercial says.

Got a call from this number on both my home phone and cell phone. Don't know who this is.

This number came from a woman who said she was with Direct TV and we were on a call that got disconnected. Oh but we weren't. Wrong number.

I got a call from this number when Verizon DSL called me back about a problem with my DSL.  It's an outsource line used by multiple companies, as you can see from the posts on here.  If you dial the number (I'm surprised I'm the only one who tried that), you hear that it's PRC/Alorica, a "leading provider of outsourced customer care solutions".
