The company is probably a fraud and quite possibly war dialing to find open connections (modem and the like) for exploitation. The particular line they use is common to corporations in that it is outbound only with no inbound services attached(hence the reason we can't call back in). more info as I find it.

this person at this number calls continuously and hangs up. I have no clue who it is, I don't even live in the city of this number. I want to be able to block this number from my cellphone!!!!!!

I received 2 calls; no message no answer.  I called it back and it states the voicemail box is full.  Probably some marketing scam.

Someone finally responded when I answered.  Foreign sounding woman (Middle Eastern??) saying she was calling from Texas (area code 201 is New Jersey) and could work with me to get money from the government.  Good heavens!  What next?  I cut her off and told her never to call my number again and that I was reporting the number that was on caller ID.  She hung up.

This number always calls. I get calls every 15 minutes from it at times.  Finally got a person, same arab woman claiming shes in Texas and wants to help me with online banking ?!?!? I told her im on the do not call list and she hung up on me in mid sentence.    This is a New Jersey prefix.  If shes in jersey calling me here in California at 11:20 PM west coast time ... Something is funny. No business calls anybody at 2:20 AM  so its got to be a scam. Mailbox is always full so nobody answers when I call back. Im going crazy, think Ill change my number if this number dosent stop calling me
