This number called my DNC listed landline today at 1252 hours.  I wasn't near the phone so didn't get a chance to answer it.  An online lookup indicated the number doesn't exist.  When I blocked my phone number and called it back, I got a message saying the call cannot be completed as dialed.  Yesterday, I received an unknown call from 860-636-5263 that also apparently doesn't exist.  Looks like overseas scam artists at work.

Called many times, no message. Blocked.

Third call from this number. Recorded message "Goodbye" then disconnect.
