Saw a missed call on the caller id, yet the phone didn't even ring. I googled the number and came here. I have a Panasonic phone as well that allows me to block numbers, but I also have call block feature on my home phone service that allows me to block the call. They'll get a recording that the party you're trying to reach is not taking calls from this number. Check with your home phone service provider to see if this a feature that you have. It's wonderful!.
