Integrated Voice Messaging Service


Service Description

Voice Mail is a computerized system for answering telephone calls, delivering a personalized greeting and recording voice messages. Voice mail is available 24 hours per day, greatly reducing "telephone tag" when subscribers are on telephone calls or away from their desks. Voice mail can be accessed in the office or from any touch tone telephone. Greetings can be changed at any time. Messages are time-stamped, and at the users discretion can be listened to, replayed, replied to, forwarded, broadcast, appended, and saved or deleted. Subscribers benefit from getting the entire message rather than an abbreviated summary, along with the benefit of sensing message importance and urgency from the caller's voice inflection.
