You don’t want to answer calls 24/7 (unless you’re serving clients globally and there’s an expectation of 24/7 support). If you’re unavailable during specific hours of the day, use the voicemail examples below for after-hours business calls.
Donald G. Gould, of Northwest Washington, is nothing if not au courant. Here's his message: "Hello. You have reached {the phone number} in the nation's capital, a city now permanently on the Dole and where even the best periodontist cannot cure Gingrichitis. Please leave your message."

A business answering machine greeting is a message recorded on the voicemail or answering machine of a company. Since this message is going to be heard by at least some of your customers, you should be sure to keep the message professional. For the most part, you should not create a message that is silly or funny, but instead provide important and useful information in a way that is professional and fairly fast. You can, however, use the message as a quick opportunity to include a brief statement about a particular service you offer such as “Thank you for calling The House of Pies, home of the world famous zucchini and artichoke pie.”
Whether it’s an out-of-stock product, a canceled event, or social media snafu, there are times when your business may see an influx of frustrated callers. While it is important to address their concerns head-on, you may not be able to answer each call as it’s received. Make sure you use best practices for dealing with angry customers, and that your voicemail greeting sets the appropriate tone. Avoid defensive language, validate their concerns, and keep them informed as to how you are handling the situation.
