The basic rule of thumb is that callers should hear one of two things when they first connect with your voicemail — either an apology for not being able to answer the call or a “thank you” for having called. You can do both if you prefer, but keep it short and to the point.
A general voicemail greeting is what callers will be greeted with if you are unable to answer the phone at work. It is the everyday greeting, used as the default, unless you have set up a temporary greeting, such as an away message while you're on vacation, or a special message during a holiday.

Below are examples of what to say in a voicemail message. Whether recording the message for a personal phone or a business line, these ideas will help. Using humor is appropriate in some situations, but humor should be avoided in situations including serious businesses where reputations could be damaged or people could become upset.
Once you finish your voicemail message, you can end on a note of gratitude and express thanks or that you realize the recipient of the message us busy, so you’d appreciate a return call. Whichever way you choose, make certain that the tone of your message is upbeat. A business voicemail greeting sees each call as their chance to engage with their clients or vendors. Hello, you’ve reached the office of Lydecker and Lydecker.
