Who called from 2136290000

Calls you, but hangs-up the moment you answer.  It seems like an automated system that is just verifying your number is real, so they can add them to some telemarketing lists to use later, or sell to other telemarketing scumbags.

today....this number called me three times....same thing....calls and when you answer there is no one on the line....

Received a call from this number.  Caller ID was Park Fifth.  Once I answered the call was disconected.

I get a call from these people. I dont answer it as my fax machine is faster than i am. Not sure what they want. It comes up PK 5th Sales of. On my Caller ID box

Did some more research and found this, http://www.parkfifth.com/ click on Contact us and you will see this Telephone Number. I guess its for some kind of Condo thing in LA area, there planning on building
