Who called from 2132334850

They called my home phone, let the phone ring and then hung up just before voicemail.  Called id showed prolly the weirdest one I've seen yet...United Voicemail.  I see this is only the second listing for this number.  Wonder what they want?

4:11 pm today.   I was out so I don't know if No mo blocked it or not.

Called on 11/2 at 5:48 PM. ID read Los Angeles.

11/03/15 17:35 PST  Another annoying anonymous call that goes through to voice mail, ties it up for several moments and then hangs up.  Give us all a break already!
