Ok, so I see many complaints, but no remedy. What is your purpose once you receive these complaints do you notify some authority, that can investigate and eliminate these nuisances. We are paying customers of whatever service provider and with technology in place, I see no reason why these unwanted callers cannot be globally blocked by the providers, rather than just wanting to issue another number to their users, which solves nothing. Any number obviously is publicly available to hackers such as this one 1-201-257-4261. My request is to report it and eliminate it from happening alltogether, or cell phone services will soon be seeing RED, because users like myself will not use them anymore and they will eventually be out of business.
Got the same call today. Missed the call and called the number back since it was in the New Jersey area code where i used to live (albeit I lived there 7 years ago and did not have my current phone number which is a SE Texas area code). Message was pretty disgusting I will admit. Really makes no sense what the purpose is, its not telemarketing or anything for monetary purpose. It says the 'subscriber can not receive messages at this time'. My guess is the voicemail box is full due to people calling the number back and leaving a messages in one way or another.
