Several calls over the past few days. I don't answer them because I don't recognize the number (shows up as Florida). I just let it go to voice mail. After reading what has been entered here, the next few calls that come in, I pick up on the first ring, but I put my TV on mute, and sit there absolutely quiet until the call terminates. Maybe they'll figure it is a non-working number. Right. In the meantime, I am having this number added to my blocked list with my phone service provider.
