Reverse lookup says the listing is "Nextiva".  Based on above comments, it is a scum Spammer and not worth my time.

A spammer

I keep getting hang ups from this number.  Caller id is showing nextiva.

Caller ID sez Nextiva but according to Google search, Nextiva is a cloud-based communications company, so I'm guessing that ID is just the system that they are using or the service provider.  Gotten several calls, but of course no messages left.
