Same here.  Number called yesterday.  I didn't answer.  No message.

Some company advertising a free wireless home security system for homeowners. I am not a homeowner. It said to press 2 to talk to an agent or 4 to be placed on the do not call list. I pressed neither and let it automatically hang up. When I tried to call back, the number is disconnected. It is probably a scam.

Answered the phone, no reply. Waited 15 seconds. Hung up. Probably an auto caller.

Caller ID says"XXXXXXXXXX  CA. Clicked "talk", then "off". Obvious scam.

Called here, nothing but silence.
