Using VoIP over Satellite

VOIP (Voice over Internet protocol) technology has revolutionized the way voice communication is done over international long distance. It is better known as Internet telephony and is offered by many service providers. The service is offered over Internet protocols and not over conventional telecommunication infrastructure.

In this age of convergence Internet telephone, World Wide Web and even video can be transferred over a single fiber cable laid underneath the oceans across continents. Using your Broadband Internet connection you can connect to any person around the world in a second. VOIP technology has evolved over time, but still there are many challenges that need to be overcome. Delay in the delivery of voice packets, congestion and the order in which packets are delivered to the receiver are some of the challenges that VOIP providers are still trying to find a solution to.

Technological innovations are happening rapidly and VOIP companies are working constantly to upgrade their technology. The services are offered over different protocols and some of these are Gateway Control Protocol, Media Gateway Control Protocol, Session Initiation Protocol and more. There are different bandwidth requirements and varies depending upon the coding algorithms that are being used for packets transferring the voice packets.

With rapidly changes in VOIP technology standardization is also taking place quickly and providers are adopting certain minimum standards to offer quality services to customers. MOS or Mean Opinion Score is one of the most commonly used Quality standardization methods used in VOIP service.

The Mean Option Score standard is based on a scale of 1 to 5 in ascending order. Globally there are many companies which provide users with free VOIP service. Some of the companies which offer free or cheap VOIP service are Skype, Yahoo, Vonage. VOIP has become one of the primary means of communication for people living in different countries. It is the cheapest and one of the best modes of communication to stay in touch with friends and relatives living in different countries.

Offering VOIP at cheap rates or free is possible because providers use underutilized bandwidth to transfer voice packets. The networks have dual functionality and can be used for data transfer also.There are different channels through which VOIP services can be offered. It can be a PC to Phone service and vice-versa, larger companies use Virtual Private Networks to transfer secure data and Wireless Connectivity.

Net-meetings, conference calls and other communication methods often take place over virtual networks using VOIP technology. In some cases VOIP is being misused by individuals and corporations to bring down communication costs. Corporations prefer to use VOIP over conventional telecommunication methods because of cost and relatively good quality.

Since VOIP companies don’t fall under the ambit of the taxation in all countries where they offer service regulators are worried that VOIP may cause huge revenue loss to the government. In countries like India where IT and ITeS outsourcing boom has made VOIP very popular, laws are being framed to prevent irregularities in utilizing VOIP services...
