Click! Hang up, perfect voicemail. You do not need to say the phone number twice.. Let’s assume you’re going to have a seven minute spiel and you don’t want them to replay it because you’re phone message is ten minutes long of course. But if your phone message is just a couple of seconds, one time is enough.
If, on the other hand, your clients work with a number of team members, you might consider hiring a voiceover professional to record your greeting. While a recording with a voice actor is an extra expense, the result often outweighs the cost.

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.
Shut the office door and turn down the music—it’s time to record! Pretend that your office is your music recording studio as you prepare to vocalize your message. Remember that obscene background noise can be a major turn off to potential customers and prospects.
