Hi, this is [your name] of [your business]. I’m currently unable to take your call. Please leave your name, phone number, and a brief message, and I will contact you as soon as possible. Thanks.
I know you probably thought of this, but did you ever record the message someplace else or possibly have it playing while shooting a home video during a birthday or an anniversary? Probably a remote possibility, but you never know. Since you didn’t record over it, there might be a possibility of retrieving it. I really hope so! Please let us know what happens.

A word of warning: These greetings will not do you any favors if you're in the midst of a job hunt or work in a conservative industry. Always remember your target personas. If there's a chance they won't appreciate your sense of humor, opt for a straightforward greeting instead.
That’s why it’s critical that each customer interaction with your business is consistent, positive, and represents the values and personality of your company. This includes your storefront, website, social media presence, emails, and every interaction you have with your customers, both online and in-person.
