If you are a friend, trying to give us money or just want to talk, then leave a message or try my cell phone number. I don’t know who you are, and I don’t know what you want. But you can tell me all of that in the message you leave me. Try These Sample Voicemail Greetings.
If the you haven't changed your personal greeting, a default system greeting will be played for callers. For example, "Please leave a message for John Smith. After the tone, please record your message. When you finish recording hang-up or press the pound key for more options."

Consider for a moment how your phone is currently being answered. Professional courtesy is quite often not the standard for many college students. An abrupt "Yeah!" could be listed among the more courteous greetings. The more outrageous remarks will often buy you a major black mark in the professionalism category—even if it was your roommate answering your phone and acting crazy. A simple "This is ____" is always a pleasant change for a college student call. Make the change today, before the next (or first) employer phone call. If you have a landline, you should also encourage your roommate to do the same.
A word of warning: These greetings will not do you any favors if you’re in the midst of a job hunt or work in a conservative industry. Always remember your target personas. If there’s a chance they won’t appreciate your sense of humor, opt for a straightforward greeting instead. “This is Bond. James Bond. Okay, it’s really [your last name]. [Your first name] [your last name]. I’ll get back to you as soon as I’m done helping M16 save the world — which will probably be tomorrow at the latest. Have a good day.” “Hmm. Gryffindor … No, Ravenclaw. Yes, you definitely belong in Ravenclaw. *Pause.* Okay, you haven’t reached the Sorting Hat — it’s the voicemail of [your name]. Please leave your name and number (and just for fun, the Harry Potter house you think you belong in) and I’ll return your call as soon as possible.” “Hello! You’ve gotten the voicemail of [your name]. Leave your name, contact info, and the answer to the eternal question ‘Which came first, the chicken or the egg?’ Anyone who gets it right will receive a call back.”
