Voice-over Internet Protocol (VoIP) and IP-telephone technologies have matured to offer businesses dramatic returns on their investments. By merging voice and data networks, IP telephony enables businesses to transmit telephone calls over their data networks or the Internet, deliver voice-mail and conference-call applications to employees’ desktops and significantly reduce long-distance and inter-office telephone charges. 

IP telephones are well suited for businesses with data lines that connect their enterprise with remote offices around the globe and for businesses wishing to control telephone access from a central location. Moreover, IP architecture offers additional business applications, including video-over-IP, which provides a centralized surveillance of video cameras, as well as video conferencing and training capabilities.
