Different phone systems allow users to see different amounts of information ranging from a number, to name and number, to nothing at all. So, this “missed call” method of requesting a call back could end up costing you the very thing you are seeking.
Wondering why this is? We can thank the serial position effect. This psychological phenomenon says when you show people a list, they'll remember the first and last items the best. That means when you're trying to grab a prospect's attention, you want to be one of the first or last things they hear.

6. Vacation Voicemail Greetings. Hey, this is [your name] at [X company]. I am actually on a break at the moment, on the other side of the world! Please direct all phone calls to [alternate contact name] at [phone number] and emails to [X email address].
5.) If you’re calling a home line, and know the family, it’s nice to say a group “Hello” before leaving a message specifically for the person you called. Say something like this: “Hi everyone, it’s Maralee. Hope you’re enjoying Spring Break! Janet, I wanted to see if you and I could meet for lunch one day next week. My schedule is pretty open, and we could pick a restaurant near your office. I know your lunch schedules are tight. I’ll give you a call back at 7:00 tonight. Or I’m around all afternoon, so give me a call!” (Boy, home lines are becoming rare, aren’t they? We gave ours up a couple of months ago.)
