"Voice mail has lost its appeal primarily because it's very much tied to the notion of the phone and your communication being tethered to a physical thing or a physical location," he says.
The most professional voicemail message should include a formal tone and specific instructions. For example, you may say “Hello, you’ve reached [your name], [job title] at [business name]. I’m sorry to have missed your call. Please leave your name, contact information, and reason for calling so I can get back to you promptly.”

Before you record a professional voicemail greeting, you may want to consider the type of people who might call your home or business. That way, you can think about the information these callers might need before you compose your greeting. Most callers are familiar with how to leave a voice message, so try to avoid giving them instructions. Some things you may want to include in your greeting might be your full name, title, name of your company, and an alternate method of reaching you. If you plan to be unavailable for some time, it can be a good idea to tell your callers when you will return and give them the name and phone number of another individual to call in the event they need immediate assistance. A private voicemail box enables a person to receive telephone messages when the phone cannot be answered.
Identify Yourself—I believe identifying yourself through your voicemail greeting shows respect to everyone who calls you. It allows your callers to confirm they have dialed the right number. When people don’t include their name in their greeting, it leaves me wondering if they have something to hide. I have seen this to be true far too often.
