Additional resources for Voice Over IP
Data networking is more efficient because we have been using data packeting for years through packets, frames or cells. The use of a packet switching transmission system enables us to interleave voice and data packets (video, too) where there is idle space. As long as a mechanism exists to recoup the information and reassemble it on the receiving end, it can be a more efficient use of bandwidth. It is just this bandwidth utilization and effective saving expectations that have driven the world into a frenzy over packetizing voice and interleaving it on a data network, especially the Internet.
This is nothing new because we have been trying to integrate voice and data for years. However, a subtle difference exists with today's convergence scenarios: In the beginning, the convergence operation mandated that data be made to look like voice; then it could be transmitted on the same circuitry. Circuit-switched voice and data used the ''age old" techniques of a network founded in voice techniques. Now, the convergence states that voice will look like data and the two can reside in packetized form on the same networks and circuitry.
The answer is a mixed bag, but overall the efficiencies of VoIP will outweigh the need to develop better control mechanisms to satisfy the telephony industry. Applications for VoIP Voice communications will remain a basic staple for the industry. The public switched telephone networks will not be replaced, or dramatically changed for that matter, in the near term. The immediate need then for VoIP providers is to deliver equal services, similar to the PSTN, at a lower cost of operation and to offer a suitable competitive product as an alternative.
