One of the most challenging aspects of writing for speech is optimising text to be read aloud and recorded. On paper, long, complex sentences are easily accommodated. When read out aloud, the same sentences can sound awkward and confusing.
The business answering machine greeting you use should be fairly short and to the point, though you can use it as a way to demonstrate what your business has to offer. Your overall tone in the message should be professional and indicate to callers that though their call has been missed at that moment, they are important and you plan on contacting them as soon as possible. Within this, however, you should not indicate that you are talking to someone more important than the caller. Your business answering machine greeting should also be customized in any way you deem appropriate for your business and needs. Jotting down the greeting will prevent mistakes when recording it.

A formal voicemail greeting is one with a professional tone. It could be for a business or for personal reasons. Formal voicemail greetings are designed to impart a sense of authenticity. They leave the caller with a sense of trust in your abilities, whatever they may be.
