this number calls me and remains silent.  The caller or the number
is unknown to me

I do not know who this is.  The phone was dead the first time I tried to answer.  After that I have not answered a call from this number.  I depend on my phone and do not appreciate callers that are not lagite.
There should be a way to stop these unwanted calls.

called and left no message

No response.

I know not who but about one or twice a month I get these calls. Wish they would find some one else to harass as I am sick and tired of it.

Called and left a one word message "hello?" ... then hung up. When called back, got a one-word synthesized voice saying "Goodbye" and then the other end hung up on me. I think the "hello?" was artificial too, now. Adding it to my block list.

Just received call....looking for a family member re: life insurance...called back...recorded GOOD BY...

didnt answer - getting these calls constantly so now I dont answer if I dont recognize - its commingle embarrassment

It's a robocall telling me they can save me money on life insurance. Blocked now.
