Did not answer but no message left. Maybe this is the start of yet another annoying robo-call assault!

All unidentified calls go to voice mail. They do not leave a message just dead air. They keep calling back, very annoying.

Same. Dead air

Don't tell these people anything! They just called our house claiming they were from the "Heart and Stroke Campaign"...it's a FOUNDATION. They wanted to know if we were home to help them go door-to-door to get donations. No charity will call you at home to ask you to work for them!!
