If you have a voice mail facility, either be specific with the information you would like callers to leave, or inform callers approx. how much time they have to leave a message. Recently I have found that more and more companies ask you to leave a message and the time I have to complete it is very short. What does this mean? To start with it means another call to your company (this may be at your cost if it’s a toll free number). It could also mean that you have to listen through 2 messages when one will suffice and it also inconveniences customers.
