No More Telemarketers!
I recently purchased a Panasonic cordless phone with automatic call blocking. It requires a caller not listed in the Panasonic's phone book to enter a simple 3 digit code to be connected. After using the code the caller will not be asked again. My phone no longer rings with unwanted calls. It is very effective to the point where my phone is a useful appliance once again.
Perhaps there are other phone brands that have the same feature. I am not "advertising" for Panasonic phones and just want to make people aware of my experience. I have been annoyed by these calls for more than a few years and this is the first satisfactory solution I have run across. I have tried blocking individual numbers, the Do Not Call List, individual number blocking and Nomorobo with poor results. This is more than just a phone blocking feature. On the Panasonic phone it is called "Automatic Call Block", not to be confused with simply "call blocking".
