For many small businesses, the announcement will send the caller straight to a voicemail box. But larger organizations may decide to direct callers to a phone menu or forward the call to an external destination, depending on the situation. These options can include: Listing individual voicemail boxes for different departments or employees. Forwarding calls to a professional answering service. Giving callers an option to connect to an after hours or emergency support line. Directing calls to a personal cell phone. Presenting menu options for additional recordings about office locations, ongoing promotions, and other information.

Choose a greeting—Default or Custom; if you choose Custom, you can record a new greeting.
Some phone systems require the recording to be on a mp3 or wav file, and some you just have to record the greeting right into your phone. This last way is likely one you have tried already.
