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.
Just like the importance of conducting yourself professionally in person and over email, you want to make sure that if an employer is trying to contact you, that they receive a professional greeting, even if you aren’t able to answer the phone right away.

You have reached (your business name). We may be on the line with another caller at the moment or away from our desk. Please leave your name, phone number, and a brief message and we'll return your call promptly
Business voicemail greetings aren’t difficult at all to optimize. What it all comes down to is being prepared, knowing what you and your customers need to make every interaction run smooth, making sure your message is easy to understand and clearly expresses your intentions, and remaining open and optimistic.
