It is important that the voicemail greeting be brief but also action oriented. Do you want your caller to leave you a message? Or perhaps they should call another extension to reach an assistant or office manager in your absence? Get to know the business phone system that you are using and take advantage of its features. Some phone systems allow the caller to press a digit, such as 0 to transfer to another extension rather than having to end the call and dial another extension. This type of function can be extremely useful, especially if other people in the office can handle the calls that are incoming to your phone while you are away from your desk, or out of the office.

Your greeting is very important as it can be the first contact people have with you or your company. Voice mail is only impersonal if you make it that way. One way to help increase the effectiveness of voice mail is to change your greeting at least weekly if not daily.
