 Voice over IP (VoIP)
VoIP is a set of technologies that enables voice to be sent over a packet network. While few corporations use VoIP today, its usage for messaging is expected to explode in the coming two years.
Users can communicate using VoIP as easily as they do with today's PBXes and public phone network. By leveraging the existing data network, companies can save significant amounts of money by using VoIP for toll-bypass, which is particularly important for multinational corporations. VoIP will also speed the adoption of unified messaging by transmitting voice, fax and e-mail messages. VoIP is also known as IP telephony.
Over the next several years, companies will deploy VoIP in conjunction with 802.11 wireless LANs, enabling workers to have WLAN-based mobile phones when in the office.
