If you are recording a voicemail message for business, be sure you include your name and your company's name, so people know who they are calling and were they are reaching them. If you do not include the business name, they may think they have mistakenly called you at your personal number. You will also want to make sure to give callers the option to speak to someone who is currently available, an operator or other representative, by pressing a certain key (check with IT personnel to see what this might be).
A secretary in a doctor’s office creates a voicemail greeting that says, “If you have a scheduled meeting with us, we could use copies of all your medical documents from last year, so come prepared.” Using the word “could” gives patients the impression that they don’t necessarily “need” last year’s documents. See the difference between “could” and “need”? Your word choice can impact a future meeting significantly. If you want a customer to perform a specific action, you need to pay close attention to how you express your calls-to-action.

Before you record your business greeting, make sure to write it down first. Finalize your script and then rehearse a few times before you record the final business voicemail.
In closing, this guide should highlight that the options for professional, friendly, interesting, impressive, and concise voicemail greetings are as broad as the imagination. Remember, the best business voicemail greetings are those that are equal parts useful to both the caller wanting a service and the recipient wanting to offer a service.
