If done tastefully, you can promote your products or services on your voicemail greeting without sounding pushy. In fact, it’s a great way to keep customers up-to-date on company events, sales, and other news. Be sure to keep it short and have fun with it.
"Hello, this is Sally's microwave. Her answering machine just eloped with her tape deck, so I'm stuck with taking her calls. Say, if you want anything cooked while you leave your message, just hold it up to the phone.'

On the Phone tab, click the voicemail icon below the dial pad, and then click Change Greetings. Skype for Business calls your voicemail and guides you to record a personal greeting.
This is the type of message you should aim for when you are recording an answering machine greeting at your place of business. Some people do need to leave other information for business salutations, such as office hours, and they may leave special messages when they’re on vacation. Name of the business, or your name can be important too, since people may want to be sure they’ve reached the right person or business. Answering machine greetings should be pleasant in tone.
