So I'm off work and I'm decide to get up, make breakfast and then go back for a nap. Only I'm woken up by my girlfriends phone ringing, and ringing, and ringing, and ringing, and ringing but she's out so she can't answer it. It's been ringing for a solid minute or so.
It reminds me of work when someone is away from their desk and get a call. People don't seem to get the concept of if they've not answered after the first 3 to 5 rings the person is probably away.
Basically;
How long do you let a phone ring for before hanging up?
Do you call back immediately after the first attempt, or wait?
Does excessive ringing get on your nerves?
