What is VoIP?

Voice over Internet Protocol is a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls. This method of transporting voice utilizes the same packet based protocol the internet uses to transport data.

Currently, the predicament with traditional VoIP, is getting the quality of the voice to attain industry standard levels. This dilemma is multiplied, because most systems in place today are using traditional Internet Telephony. Internet Telephony transports the voice packets over the Public Internet. This method of transport is suitable for the less time sensitive data applications, but is exceedingly inadequate for the more time sensitive applications such as voice and streaming video.

There are three pressing issues that keep the quality of VoIP from being what traditional POTS lines offer:

1) The internet is a “Best-Effort” network, which means there is a considerable amount of packet loss and latency (time it takes a packet to travel from source to destination) which cause inherently poor quality of voice.

2) The problem, however, originates at the source of the call (ie. the kiosk). This means that if there is a significant amount of data being transmitted or received at the same time there is a voice session, the voice packets will have to “wait their turn” behind the data packets, increasing their latency and minimizing their significance. Clearly, the end users will not tolerate this delay, because the quality is dependent on the latency.

3) The method the Voice is packetized is also very important. Currently, most VoIP providers are using some sort of software compression to do the packetization. Unfortunately, although this is an inexpensive solution, it is not the most effective one. The software compression has many flaws and errors and does not create the purest packets for transmission.

In order to decrease the degradation of voice, TNS has developed a process patent pending solution that will eradicate as much of the above issues as possible. By using our technology and strategically placed networks, TNS has attained its goal in creating the highest quality Voice Enabled Public Access Internet Workstation in the world.
