Received this call and of course no one answered . Probably spam again.I got a new blocking caller id , so far it worked one time. Now I can add it to the list of others telemarketers. It is suppose to hold 1500 telephone numbers. Won't take long till I start adding the new telephone numbers in it.

I went on the webside, ringcentral.com, and the person answering the phone said they did not
know who made the call.

I got a call from this number and it referred me to ringcentral.com

it's a strip club in detroit. if you used a credit card there you are in a drawing, i won a new 19" tv

Keep getting calls from this number with no one speaking when I answer.  How can I block such calls?

Just received a call from this number, we answered it because its local to us, there was no one there. We called them back and got a message from something called Ringcentral.com. Apparently someone is trying to set up their own telemarket thingy and its not working out for them. LOL

From the website:

*Many locations. One phone system.

"Since RingCentral is cloud based, you enjoy the freedom to connect and manage multiple locations, devices and workers within your cloud phone system. You can easily customize users, departments, and call handling rules. No matter where you, or the users, are."

Will be blocking this number!

They left a voicemail but it was a two second empty message

Received a call from this number at 10:58 am on 11/21/2012 and this is not the first time
we received a call from this number.

Hello?  No response.  9:57AM

Received a call no one answered back... Hate those kinds of calls ... Been getting them alot lately..

Received a call from this number a few minutes ago. Husband answered and no one responded. Doubt it was an "if a man answers, hang up" kind of call.
