All companies should have professional voicemail greetings. It’s important that all voicemails are professionally-read and sound consistent across each department. This provides the caller with an elevated experience, setting them up for success on every customer interaction.
Another way to make up funny voicemail messages is to act like a device has come alive. For instance, you could say,"Hello, I'm Bob's hair dryer, and I've taken over because I'm way more interesting. If you'd like to leave a message for him and have your hair dried at the same time, just hold up the phone." Answering like an answering machine, a microwave, or refrigerator and using the functions of that device in the answer are easy ways to create a fun voicemail.

Businesses should have two main types of greetings to create an excellent call experience. The first one is what we call a “welcome greeting” – this greeting welcomes callers to your business. Typically, a welcome greeting will present a menu of call options like hours, location, or customer service.
