I’d like to see a password option. Someone calls you and has to put in a secret 4 diget number to make the phone ring, otherwise it goes to voicemail.
Google Voice.
I use Google Voice on my resume as a first-line defense against Indian Recruiters who do nothing but waste my time.
T-Mobile marks some of my calls as “Scam Likely.” I like that feature a lot.
Sentry is even better than a password. When a call connects, a recording says that to continue, press the zero key. Robocalls virtually never can do that. Then the call terminates. My phone never rings unless zero is punched.
If the number is blacklisted, it doesn’t even get that far.
But with this system, there’s really no need to blacklist, anyway.
