That is the exact opposite of my experience. One of my Doctor's hired a new College aged girl in her office. I was in there when the other office staffer had her calling people to change appointments. She questioned why the girl wasn't leaving messages and the response was "they will see they had a missed call and call back". The entire concept of leaving a voice message was something she had no experience with. As the other office staffer told her most of our patients as elderly, they have landlines, they don't have caller ID, they have answering machines and expect a detailed message. All she got was a "deer in the headlights" look from this young lady.
At 65 I'm not young, but I spend a career at work having to leave voice mails and I always leave a message, I always repeat my phone number and say why I called (contrary to those Progressive Insurance commercials that make fun of that).
And I used to HATE it when I would get a call at work and someone would say "I just got a call from this number". For security reasons our main number was what was displayed but there are 120 people in the building, so I have no idea who called. And then I ask "did they leave a voice mail" and I get the response "I never listen to voice mails". Really? You'd know who called you if you did.
