This # calls to my phone five  times,  every night !!!!! And I have virgen mobile.

I was able to stop this only temporarily by Verizon Wireless, I am now being subjected to the same calls, 5 a night starting at 12:09 and repeating every 10 minutes.  They now will do nothing for me to stop this harassment.  Police could care less, basically laughed at me.

I called cablevision to block this number about a month ago it stopped and on 4/19/2011 it started they blocked it again and i just received about 6 calls on 4/20/2011

Who was it?

Yes, Joey M is correct.  After going "crazy" trying to figure out who the hell this is - The DAWN came!  While I was on a call that I made - I heard the call waiting beep - I did not take the call.  Checking the time that this happened this would make perfect sense.  To bad the company representatives don't have the knowledge to answer this simple question.  (simple when you finally figure it out!)

The number is from Optimum Voice.  To make it stop calling go to Optimum Voice website http://www.optimum.com/voice/index.jsp . You will have to log on to your account and disable the urgent message notification. Follow these prompts: Voicemail / options / Notifications / !Urgent Message Notification / Off . That will stop the madness.

It is Optimum Voice letting you know there are calls in your home number voice mail...I'm now sure of this.

F***'n calls me every night on my cell, about 4 or 5 times.  If I get my hands on the M'Fckr that is doing this I am going to choke the mthrfkr to death.

This # calls my cell 5 times every night. Always leaves messages about a mailbox being full. VERRY ANNOYING!!!!

Found this number on my bill as well. Its weird. I ran it throught Intellius and it shows as one word MONICA in lindenhurst

did you ever find out what this numver is?

I repeatedly see this on my bill.  It is the optimum voice mail number.  I do not know why it keeps appearing because I never use that voice mail.  Optimum says the only way for it to appear on my bill is for us to either dial it or to dial our own phone number - neither of which we have done

631) 412-5800Provider: XO
Location: Lindenhurst, NY

I keep getting calls from this number stating my mail box is full and to press pound to discontinue messaging - I than check my mail box and this is the only message- I spoent hours on the phone with VERIZON THIS IS NOT A VERIZON MESSAGING CALL NUMBER- IT BELONGS TO A SPRINT CUSTOMER- I WAS FURTHER ABUSED BECAUSE I HAVE GOTTEN THESE CALLS AS LATE AS 2:50 AM-IF ANYONE FINDS OUT WHO OWNS THIS NUMBER PLEASE ADVISE-THIS IS CYBER HARRASSMENT- VERIZON WOULD NOT DEAL WITH IT THEY WANT THE CUSTOMER TO FILE A POLICE REPORT.

i called Optimum Voice about this. well they told me that this number is the voice mail access if you have Optimum Voice service in 631 area code. so if you have Optimum Voice phone service this would be the number to call if you live in 631 area code to access your voice mails..

i dont know why its on my phone i live in 516 area code and we have a different access number.

We found this number on our bill. We did not call this number. When I attempted to call these folks, a recording instructed me t enter my 10 digit phone number and then  press #. Of course, I am not so trustworthy that I would have done so. I fear they may be trying to do something like spam mail...use my phone number to bill calls to for the purposes of solicitation.

What is it with this phone number?
