When creating your after-hours business voicemail greeting or auto-attendant, be sure to explain the hours your business is typically open and any potential conflicts with that schedule (like upcoming holidays or business closures). If your business could benefit from more than one menu option or message use an auto attendant.

When you create a professional voicemail greeting, it can be a good idea to think about what your callers might want to know. After doing so, you can make a list of points to cover in your voice message; it might also be a good idea to write out the entire greeting on a piece of paper. The ideal message should be somewhere between 10 and 20 seconds, so you may want to time yourself repeating your message before you record it. After composing your telephone message, it can be a good idea to get a second opinion of this greeting so you can make sure it sounds professional. Writing down a voicemail greeting helps prevent mistakes when recording it.
