I have received the same call from "Dan the carpet cleaner".  

I have also filed a complaint with DoNotCall.gov.  I would encourage all of you to go to the website and file complaints of your own.

didn't answer the call...

Receieved a call this morning but I wasnt home, they left no message but the caller ID read J2 Global Commun. I called it back and the message said not in use. I did a reverse lookup and its a unavailable landline number. I am also on the DNC (do not call) marketing list. Thanks to the yellowpages pulling up this website, now I know who to avoid or fuss at if they keep harrassing my phone.

I got a missed call from this number, no message, and I am on the DNC list.

Complaints alleging violations of the Do-Not-Call registry should be filed online with the Federal Trade Commission at www.donotcall.gov  or by calling the registry’s toll free number at 888-382-1222.

I am not on the "do not call list" as those lists are sold to business' and many of them (I suspect) may use them to find your number. I've given my cell number only to friends and family and my work. I've had this particular number for 5 years with only 4 telemarketers calling me. Much better when I had my other number that I registered with Do not Call Registry and received tons of telemarketers. Since that time, I've created a contact named "blocked" and the telemarketers number added to it and a silent sound attached to the ringer for that number. Works out pretty good.

I don't believe any phone company would provide a block service for your cell, it's goes against their $$$interest to burn your minutes.
