Same here, same as every number I don't recognize. This is the first place I go to check. I used to give them a different ring tone, but they're onto that so they use 10 different numbers. No bother here. I don't answer. This is a great help and saves me an incredible amount of time and aggravation.
Call came in at 945 am on 12/27/2016, after the standard salutation there was dead air on the line, didn't pursue any further, reason being if the caller dropped dead laying with the phone in their hand it's already to late for an intervention of assistance. That's all. //end
