Now, here's where the embedded commands begin. I don't know if you've ever heard of Neurolinguistic Programming, NLP. I'm no Ninja at it, but I've learned a little bit about it through the years and if you can embed commands that aren't direct commands, not explicit, I'm commanding you to do this, but a subtle statement of a thing that embeds as a command to your subconscious mind, it can have an influencing effect on the other person.
Hi. This is Kevin and Diana's vacuum cleaner. Their appliances have switched jobs again, and I get to answer the phone 'cause my old job sucked. So leave a message after you hear the beep, and you can be sure it's in the bag.

Made famous by George Costanza as you can see the clip here, the answering machine song may seem like a good idea. It's out of the box, unexpected, and definitely a novelty, but unless you're in the music business, it's probably not a good idea. You'll definitely irritate your mother (or anyone else important who calls you frequently) and you won't make a good first impression with your message.
The bottom line is that a business’s situation is likely to change often and rapidly, each of which need a unique and applicable voicemail greeting to cover the circumstances and timeline. For example, callers shouldn’t reach a business-as-usual voicemail, and therefore expect a return call within the business day, if the subject they’re calling is out on vacation for two weeks. Such a lack of communication is a recipe to lose that caller’s trust and tarnish the brand’s reputation.
