We missed a call from this number on one of our business lines. The call showed up as out of area. When we called the number back we were played a recording of people making monkey noises.

Same here with the monkey noises.

received several calls from this number, but did not answer

I too have received several calls from this number.  Thank goodness for caller id.  It comes up unknown name with the number displayed, so I refuse to answer.  Last night a lady said "HELLO" on my answering machine, but then hung up.  What happened to the "National Do Not Call Registry"?  I've registered my number several times, but still get calls like this one.

the DONOTCALL registry ONLY WORKS when you ACTUALLY take a minute to report these illegal calls.

They DO NOT KNOW you are receiving these calls until you do YOUR PART!  

ITS YOUR RESPONSIBILTY

Truth about donotcall laws


Also remember that illegitimate companies and scam artists won't respect these lists.

Therefore once your enrollment goes into effect you should be extra careful of unsolicited telemarketing calls unless you know they come from a company with which you have a legitimate, established relationship
