The caller continued to ring back my phone repeatedly and I did not answer.  I reported this abuse to the annoyance call registry.

yep, they are trying to sell some quik slim product.  told them I wasn't interested and hung up on them.

Just got a call from these guys. "Calslim"...?? Tried to pitch me on a weightloss supplement but I said "no thanks" and hung up.

I just received a call from this number, he was trying to say he was from Microsoft.
Keep saying he would have to LOCK my computer if I didn't do what he wanted. I asked him what computer he was talking about, he just kept saying the windows 7 computer. I said yes I'm running  the Windows program but what computer are you talking about. He could not give the IP address of my computer. I told him to go ahead and lock it I wasn't falling for his scam.  Good thing I do have some computer knowledge. Don't fall for it, ask for the Microsoft phone number. They can't give it.

Answered: Hello. immediately hung up. funny tho... on disconnect, immediate "busy signal"
