Are you required to have a "professional" voice mail?

Well ask yourself this question, "Would I want my superiors, subordinates, or peers to hear Darth Vader on your voicemail?" No matter how cool it may be, you just never know who is going to call. Professional, no...adult, yes

Your voice mail greeting is a reflection of you as a person - how do you choose to present yourself to the world?

If you phone and phone service are paid by you, you are not required to have a 'professional' voice mail. However, your voicemail might have a negative impact on you.
