State the purpose of your call. In as few words as possible, state why you’re calling. Is it in regards to an interview appointment? Are you following up on a previous meeting?
Have you noticed how I slowed down towards the end of the message? I spoke slower and clearer. This is because when the person on the other line hears your message, they will be writing down your details before calling you back. Let’s make it easy for them to call you back!

This can also work with your iPhone or Android, if the above methods aren’t working for you. Just connect your phone into the computer with a 3.5mm audio cable. More on that in a minute.
Increase the odds of getting a call back by mentally composing your message before each call. And remember, people hate it when callers state their name and phone number too quickly in voice mail messages – no one wants to listen to a message ten times to comprehend simple information. Begin by saying your name and company (if applicable). Then assume the person you’re calling doesn't have your number, so say your phone number twice. If your name is at all unusual, spell it the first time you say your phone number. Talk slowly like you were writing it down yourself. The second time you say your phone number, you can say it at your normal rate of speech. A gracious phone message is no longer than 30 – 45 seconds. Be pleasant, but also get right to the point. Keep your voice mail message to two points maximum. If you need to share more information, then say you will send an e-mail message with the rest of the details. Leave a specific message. There’s nothing more frustrating than a voice mail that says, “Hi, it’s me. Call when you can!” Even if you’re just calling to say “Hi”, tell them that in your message. End on a high note! You don’t necessarily need to say “Goodbye” at the end of a voice mail, because you didn’t really talk to anyone. Instead, try something like, “Look forward to talking* with you!”
