            In past few years, data networks have been growing at a much faster rate than that of voice networks. This continuing trend is most commonly attributed to the rapid growth of internetworking services. Before long, the amount of data traffic will exceed that of voice traffic, although voice is becoming more popular as the technology continues to develop. As a result of this trend, the commonly sent voice signals are overlaying data signals more than ever before. These networks are to include Voice over Frame Relay, Voice over IP and Voice over ATM. Moreover, the emerging technology has been most easily evident via the use of V.34 and V.92 modems, where data is sent over a voice signal.
             As Frame Relay was introduced in the early 1990s, data technology was not originally designed to carry voice. Despite a numerous amounts of valid uncertainties about the reliability of voice over frames, the promise of "free voice" eventually proved too glamorous. It wasn't long before the modern world began to see users conducting experiments trying to transport voice over their Frame Relay devices, while equipment vendors worked overtime to make the promise of quality voice over Frame Relay (VoFR) a reality. According to the http://www.protocols.com/voip.htm site, as the public Internet exploded in the mid-1990s and users began implementing IP-based networks, thus the need and desire for Voice Over IP networks grew stronger (VoIP). Voice Over IP Networks thoroughly explored the potential and increasing demand for delivering Internet-based telephony as the next technological and profitable frontier for every company running a TCP/IP stack network. Up to now, the Internet has run over phone lines, but VoIP technologies reverse this trend by providing telephony services over the Internet. Furthermore, equipment manufacturers developed products to enable inexpensive, universal voice over data networks.
