As mentioned above, it is extremely important to have a voicemail message that is easy to understand. However, there is also the matter of word choice. You must ensure to give attention to what your words are in your voicemail greetings. There can be certain words used that may trigger your customers. Though you did not mean what they understood, it will still bring a bad name to your company’s reputation. Your choice of words can affect significantly, so make you give close attention to your words.
If you’re out of the office, a voicemail greeting will essentially act as the first line of communication between you and clients or potential clients. So of course, this could be a great opportunity to add a hint of personality, while of course still remaining as professional as possible. That doesn’t mean you can’t have some fun with it!

One way to avoid this is by writing a script. When you’re writing a script for your business voicemail greeting, make sure to look over it to see if there’s any slang or business jargon that could mean two different things depending on your point of view. If there’s any potential for confusion, revise the script and simplify the language. You can always ask a friend you don’t work with to see if your message is clear as well.
If you want them to leave a voicemail, tell them right from the beginning, “Please leave your name, reason your calling, and the best way to contact you.” If you want them to call you back during normal business hours, tell them, “Please call back during normal business hours.” If you want them to call back prepared for a lengthy conversation, you can say something like, “Please refer to our website’s FAQ page,” and then provide the URL. Self-service should never be underestimated.
