Let’s be honest, you (hopefully) set up your voicemail when you first got your phone, and it probably hasn’t changed since then. If you’re about to start job-hunting, now is the perfect time to refresh your professional voicemail greeting.
Provide a Description for this mailbox, for example "SalesVM". If you wish to customise the greeting customers hear, select the Greeting dropdown. You can either select an existing audio file on your PBX, choose a file from your computer (New Sound (Upload)), or use your phone handset to record a voicemail greeting (New Sound (Record)). This is useful if you would like to replace the default unavailable message with a personalised greeting, for example "Thank you for calling the T-Shirt company. We're all on the phone, but please leave a message and we'll get back to you promptly".

Even in today's fast-paced world, customers don't like being greeted with an automated message. According to the New York Times, callers of a certain age are put off entirely if they are answered by a voicemail instead of a real person.
