Call the number back and there is an option not to receive any further calls.  

That would make sense because I ordered some blood pressure medication and antibiotics without a prescription and now I constantly get calls from this number.   They called today and 10 minutes later called back but I refuse to answer any of there calls!    I dont need Viagra and they talk so weird hard to understand them.    I got a good doctor now so I do not need to buy blood pressure medication illegally anymore

Our phone numbers are all registered with the DOC Registry and we still continue to receive numerous calls everyday from this and many other numbers.  Usually after the third ring, they disconnect or let the answering machine to pick up and then wait several seconds after the greeting to hang up.
