Cool! My first spam message on an office telephone!  Why my cell phone has been a nearly daily victim from spam numbers and not my office phone has been a mystery to me.  1st call from this number, voicemail was dead air.  2nd call left no message.

They just called for the 3rd time, he said he was with Vonage, he asked to speak to a person (by first name only, an unusual name I didn't note down), I said "I don't know who that is, this company has over 50,000 employees".  He thanked me for my time and wished me a great day.  I didn't even have to lie, LOL.  We'll see if they keep calling.

Received a call from 201-285-5421 on 6/12/2014 at 3:08pm EDT. Caller ID displayed "Vonage". Did not answer and no message was left.

Based on the comments posted here I have added this number to my GV block list.

A hang up call from New Jersey. I'm in Florida...

Did not answer. No message left.
