This is a live caller sales call.  you can hear the other workers in the background.  these people call this house every single day.  We are on the do not call list, which doesn't work very well, and no matter how many times we ask them to take us off their list, they don't.  We are going to change telephones, and get the panasonic one which allows you to block 250 numbers.  We are not young and these constant calls are extremely burdonsome to us.  now we just pick it up and drop it back in the cradle, but still, you have to get up and answer it.  It seems you can't back track it.  We have tried.
