Voicemails don’t necessarily have to be monotonous or extremely jazzy or funky. What you should be looking for is a balance between the two. Whenever you call someone and their voicemail greeting is playing, it tells you a lot about who they are, as a person. Which is why, you’ve got to put a little bit of “you” when it comes to voicemail. And the best part about all of this is, since you couldn’t come to the phone, at least the callers are having a good time listening to the message.
10. "Hello, you've reached [X company]. We can't take your call right now, but please leave your name, contact information, and reason for reaching out, and one of our team members will be in touch within 24 hours."

Note: If you are recording the greeting on the go using your phone, please ensure there is a default greeting uploaded in the corresponding Auto Attendant menu. It is possible to record a new one only with a temporary file being there. If you have already deleted it and you are recording the greeting via your phone, simply upload any audio file to the menu. It will be replaced with your actual message once you record it.
