AIBU to expect callers, to leave a voicemail if I am unavailable?

[NeedToTakeTimeToChill]

AIBU to think, if you have called me and I didn't answer, LEAVE A VOICEMAIL MESSAGE.

Back in the day, if I called someone up, and they didn't answer, I responded to their answer machine message with "Hi this is NeedToTake, please give me a call back on XXXXX XXXXXX", or maybe a bit more detailed if a work call.

Why do people no longer do this? Why do I have to play the - who has called me game? or call the number and say "someone from this number called me" only to be told they haven't a clue what I am talking about.

So, I had a hospital appointment last week and had to have a biopsy. I'm waiting for the results. So last night at 6.30pm I got a call from a hospital I've never been to (not the one I went to, so it is a bit mysterious). It went to voicemail but left no message. So I called the number back and no one had a clue what I was talking about.

And so, I spent the whole of last night stressed out. Why are they calling me up? Is it about my results?

This morning I called it again and no one has a clue. So I have to play the waiting game again and I have spent the whole morning with my phone in my pocket at work.

AIBU to think this is what voicemail is for, and leaving a basic voicemail message if you have called someone is just basic manners.

I would never leave a voice mail I’d just send a text or whatever if I couldn’t reach someone. I also don’t ever listen to my voice mails I just leave them to auto delete

Voicemail? Is it 1998? I never leave them. If I’m trying to get hold of someone urgently and they don’t answer, I will text them a brief message.

Why stress about it? If it's important, they'll call back. It's probably an old mate using her new work phone.

I highly doubt leaving a v.mail is ok with a hospital.
Even in a dofferent country to the Uk.

Where I work it wouldn't be possible to send a text message. I leave voice messages as it's important that they know I called as there can be consequences for missed phone appointments.

I'm the opposite
I can see you've called, I have the number, I can call back.
If it's a withheld number then I'm unlikely to want to engage anyway.
Nhs generally doesn't withold number where I live

If it was important a voicemail or text message would help but I presume due to pricacy they wont

if not there is no need to leave one if they were able to do so
