That can hurt your bottom line.
Many people dislike using voice mail systems.
Their distaste is heightened even more by companies that throw customer service concepts out the window when they activate their systems. If you must use a voice mail system, make it as user-friendly as possible. Offer callers a short list of no more than four or five menu options. More than that, and their attentions can wander. They end up irritated because they don't know which option they should press, and it is irritating to have to listen to a list of menu options for a second time.
