Here are a few voicemail message examples you can record if you have the opportunity to leave a professional sounding message, while still having a bit of fun. Before choosing one of these options, be sure your company allows for a little creativity. If you work in a strict professional position, theses options might not be the best for you.
Hello, it’s obvious you have bad timing, because nobody is home. Please leave your name, telephone number, and a brief message in a voice similar to mine, and your call will be returned as soon as humanly possible.

Friends and colleagues speak to each using first names only. So do people of authority. They do not call each other and leave voicemail messages asking for Mister, Miss, or Mrs. Therefore, when you call a person you want to do business with and you leave a voicemail message, refer to them by their first name only. Don't say mister, miss, or misses. Don't say their last name. Begin your voicemail message by saying only "hi/hello" followed by the person's first name. Or, you can even forget the "hi/hello" and just say the person's first name. That is how you show confidence and authority and separate yourself from weak salespeople.
Here's the problem with recording elaborate joke messages on your answering machine: Your answering machine will become more popular than the person who owns it. Friends would tell total strangers to call my number and listen to the new goofy message. They would become disappointed if I actually answered the call first. I would have to hang up and let the machine pick up just for other people's entertainment. Dozens of people were finally calling my home phone, but few of them wanted to talk to me personally.
