It enables me to leave a longer message than I could leave with a person who might shorten or transpose the message anyway. Voice mail cuts down on telephone tag, too. But be sure to keep mailboxes empty. Something is wrong organizationally. Lack of interest in the way the phone is answered.

Make sure there's energy and a welcome with how the phone is answered. Not enough people willing to answer the phone. Everyone should pitch in to answer the phone. Also look to see if you have too much activity crowded into one job or location. Unscramble what you can.
