An auto-attendant message is the first interaction your customers or potential customers will have when they call. With today’s robus phone systems, don’t miss the opportunity to maximize caller interaction. With a well-produced phone menu, you can demonstrate your organization’s proficiency, reduce call wait times and reduce the amount of time spent routing callers. Route callers to the correct extension Prevent misrouted calls and reduce caller frustration Free up operators and agents to perform more productive tasks Conveniently route multilingual callers to an appropriate agent or telephone interpreting service Impress callers and reinforce company reputation with a voice that represents your brand

Many callers will be respectful of your wishes and follow your directives. This is extremely vital for reducing your voicemail volume.
@Fa5t3r - I would try a wide range of different tones when recording and play them back to see what goes over the best and what projects the image you want people to hear. Remember that some people may be going to hear this message over and over again depending on how often they have to call you so you want it to be very pleasant and not at all irritating.
