9722669977 is a telemarketer and now that number is blocked via the big red button on my CPR V5000 call blocker. I'm on the do not call list, but as we all know it doesn't work. These people just thumb their nose at the law that the Obama administration's DOJ refuses to enforce. I've blocked 300+ numbers, but every couple of weeks they find a number that I currently don't have blocked and call. I just hit the big red Block Now button and that number is history too. Between my phone and call blocker box I can block 1750 individual numbers or block entire area codes along with voip, international, 00international, unknown, private and unavailable calls. If you're sick of these loser telemarketers, crooked bill collectors who call wrong numbers, scammers or robo callers goto Amazon.com and check out the CPR V5000 call blocker. I'm using it on Charter Spectrum Cable's VOIP phone service and it's definitely brought alot more privacy back to my home phone service.
