Many readers who have a good understanding of the Internet and data communications technology may have little background in transmitting voice or real-time imaging in a packet-switched environment. One of the main sources of confusion for those new to VOIP is the (natural) assumption that because digitized voice travels in packets just like other data, existing network architectures and tools can be used without change for voice transmission. VOIP adds a number of complications to existing network technology, and these problems are compounded by security considerations. Most of this report is focused on how to overcome the complications introduced by security requirements for VOIP.

For several years, VOIP was a technology prospect, something on the horizon for the “future works” segment of telephony and networking papers. Now, however, telecommunications companies and other organizations have already, or are in the process of, moving their telephony infrastructure to their data networks. The VOIP solution provides a cheaper and clearer alternative to traditional PSTN phone lines. Although its implementation is widespread, the technology is still developing such like small business VoIP. It is growing rapidly throughout North America and Europe, but it is sometimes awkwardly implemented on most legacy networks, and often lacks compatibility and continuity with existing systems. Nevertheless, VOIP will capture a significant portion of the telephony market, given the fiscal savings and flexibility that it can provide.
