  1. I keep getting calls from someone after blocking their number. My phone doesn’t ring it goes straight to my voicemail and it looks like it’s coming from another state but there is no number so I can’t block it. Forgive my ignorance about these things but I don’t know what this is or how to stop it.

  2. I have used Hiya for several years. It was developed by Alex Algard, who also developed the White Pages online app which offers information on name – location – etc. of everyone in the country from publicly available sources… perfect starting point / background / data for call screening. Hiya allows blocking of area codes (for me .. 614) and “local area codes” (first six digits e.g., partial numbers .. e.g., area code plus next three digists (for me .. 614 (315). With transferability of cellphone numbers all over the country area codes and “local” area codes (first six) are becoming less meaningful, meaning if I moved to “Tucson AZ I could keep my central OH number. This is not germaine to the point on using Hiya … since you can block area codes, six digit area codes, and individual numbers. I currently block around 230 area codes. A lot of the scam calls come from Florida, California, New York, Chicago, etc. and I block around 36 entire states. Now receive much less scam spoofing calls.
