Fantastic.  I'm going to check that out.  I have been using a less high tech method.  I have an old referee's whistle. Get someone on the line then give a loud blast on the whistle.  Listen while they scream!  It provides a great feeling of joy and fulfillment.

This number called me this morning.  I'm on the Do NOT call list.  Didn't bother to answer.

They called me at 09:20 am on a Saturday morning, and woke me up.I have call blocked the number now.

medic alert trying to sell stuff

This number has called THREE TIMES.  Even after selecting the choice to be removed from their list, they KEEP CALLING.  I want to reach down the phone line and... well, you know....this is some scammer trying to scare old folks into giving up their personal information, and ultimately their money.  For that reason alone, they deserve to be dealt with severely.  This number needs to be shut down immediately for abuse.

They called and when I picked up they hung up! They called on another number four times and I contacted them and they were to take me off their call list. It looks like they are trying to create a medic alert !!
