Received a call from this number with the caller ID of "T SS LLC" yesterday. I answered the call and they asked for my husband by name. I said he wasn't available and could I help. He went into a script about renewing an old subscription to Atlantic Magazine. My husband cancelled that and went digital years ago. I asked him to hold on while I hung up another call so we could talk uninterrupted. I then hit #2 on my phone which adds the active number to my call blocker and hung up. I watched my phone and sure enough he called back. The screen on my phone lights up, logs the caller ID info and then disconnects the call. Best of all it doesn't ring.....not a sound! I love my new call blocker, I love scrolling through the caller ID and seeing all the calls that were blocked. Silence is wonderful! By the way this wonderful machine is a CPR Call Blocker Model V202, $85 from Amazon. It will block 1200 calls so it has plenty of room and was very easy to set up.
