And you’re done! Your CenturyLink voicemail is now set up. Whenever you have an unheard message, you'll hear a stuttered dial tone when you pick up your home phone.

This will ensure your voice is clear and easy to understand. While clever greetings can be fun, it's worth taking a moment to think about the range of potential callers who may be leaving you voicemail. Consider the tone and image you want to project. Don't worry! If you don't like your recording, you can erase it and re-record as many times as you'd like.
