I generally don't answer the telephone (landline).
You can't call me (yes, this means YOU).
If nomorobo doesn't cut the call, it generally goes to the answering machine (unless I recognize the number).
Spoofed calls "ring around" nomorobo (because they're not in the database), but again, after 4 rings, the answering machine picks up. Because they're robots, no message is left and the call ends.
A lot of times I don't even bother calling back those who do leave messages. That even includes friends. I'll respond to their msg with an email.
As you may have come to think, I DON'T want to talk to you on the phone.
That means EVERYBODY.
I have a cell phone -- an OLD flip phone -- but it's always turned OFF, closed, and put away.
Only there to call 911 if I'm on a trip and need it.
