Get rid of annoying telemarketer calls once and for all. This nifty little device plugs into your phone cord and only intercepts computer-generated calls – indicating this number is disconnected – which automatically takes you off their list. Over time, calls dwindle until you are practically telemarketer-free. Other incoming calls are not affected. When first introduced, millions were sold. Ever since, this product has been “flying under the radar.” However, the original and an updated model can both still be found at www.amazon.com and via online search engines at prices ranging from $40 to $10. It’s worth the effort – I wouldn’t part with mine. Additional info
