Voicemail is the same as answering. Confirms thathe number is working.
Long ring until answered also indicates a working number.
(I, nothey, am the one who does not say anything.)
I have considered recording the 3-tone Disconnected No Longer In Service on our voice mail. Then leave the telephone off the hook.
Using No Answer Transfer, the cell phone can forward an unwanted call to DNLIS ! You can see the number calling and press REJECT.
Buthe problem remains that I may be sleeping after an all night medical transport.
That call still has awakened me. Since I am on call, I cannoturn off the cell phone.
