Called my cell. Said they were selling home security systems and to press 1 to order. I pressed 1 and the call disconnected. I already have a home security system and was going to tell whoever I spoke with to take me off their call list ASAP.
I called the number from my employer's phone. (blocked caller ID) and the message said to press 1 to be placed on DO NOT CALL list and allow 24 hours to process request.
called my private cell that is registered on the DoNotCall.gov site. Didn't answer, luckily I can google faster than it takes for the voicemail to pick up. :)
