The downside of maintaining a home or cell phone is receiving annoying and unwanted calls. Even if you are signed up with the Do Not Call Registry and use the call features to block calls (only 10), you still get these type calls. I used a call blocker when I was on copper and it didn't work that well. It seems like the telephone company is is the best position of doing something about it but doesn't. Why doesn't Verizon offer something to its customers that will allow them to receive only the calls they want. Verizon can hardwire its switches with call blocking apparatus to make these calls a thing of the past.
