This is the number of the "Jolly Roger Telephone Company" Telemarketer Autoresponder.  It is meant to be a forward and/or conference destination when telemarketers call you.  It never calls out.  See http://www.jollyrogertelco.com/ for details.

I also received a call from this number on 09/13/2012.  It went to voice mail but only static recorded.

I received a call from 214-666-4321 on 09/13/2012 at 1:58pm.  It went to voice mail but only static recorded.  A different website said it was an unsolicited insurance call number.  I have my phone listed with the "No Call" service but obviously that isn't stopping this particular low life!

It's an auto insurance company. It didn't specify a name. I took the call to tell them to remove my number, but as soon as I heard the sounds of the call center kick in the idiot on the other end disconnected the call. I guess they didn't want to make a sale. LOL.

This is really great - NOT a telemarketer, it's a robot that can RESPOND to telemarketers.  SAVE THIS NUMBER ;o)

Next time someone calls you for sales purposes, simply tap "add call." Dial 214-666-4321. Merge the calls. Then the Jolly Roger Telephone Co., a voice recording that will frustrate and confuse that telemarketer, will take over.

The robot was created by Roger Anderson, who now has a YouTube channel where he documents various telemarketers encountering his robot.
