Voice over IP (VoIP) involves the transmission of voice and fax information over packet data networks concurrently with traditional data packets. VoIP provides many benefits for all levels of users, from networking equipment manufacturers and designers who are providing next-generation equipment to service providers, who are marketing these services to business and home users.
VoIP offers end-users three major value components:
Cost Reduction ? VoIP eliminates the use of circuit-switched networks and the associated per-minute long distance fees. Users enjoy a flat monthly Internet access fee. VoIP also reduces infrastructure cost by converging voice and data networks and more fully utilizing available IP bandwidth.
Advanced Applications ? Because VoIP utilizes a compressed and packetized digital format, the potential for advanced multimedia, multi-service applications are virtually limitless. These include Web-enabled call centers, collaborative white boarding, remote telecommuting and personal productivity applications such as unified message handling.
Simplicity and Robustness ? One device supports voice and data communications and this can result in elegant and simplified infrastructure designs. Integrated networks can also enable dynamic bandwidth optimization and fault-tolerant designs.
