I have been using a Google Voice number for several years. My business number is a Google Voice number. Blocking numbers, forwarding calls, personalized voice mail, etc. etc. are all handy features. When I retire in 3 months, I will forward it to some pay phone in the Arizona desert and retire in peace.
A great app for Android is the free app called “Mr Number”. It has a very easy way to block individual numbers or entire area codes. In about 5 minutes, I blocked all the area codes from the Carribean, stopping all those scammers. This morning my phone rang a partial ring and hung up. The alert from Mr Number indicated that it was a reported telemarketer. All the well known telemarketer numbers are blocked. Love the app.
Ha! Good luck finding a pay phone.
