Most people do not know what a VoIP call is, but they make them all the time. When you place a call long distance, there is a high chance that you are using voice over IP phone systems. The majority of VoIP companies provide amenities that regular phone systems do not and they have a number of advantages over circuit switching. It is possible to put in several phone calls in the same space that would occupy a number of circuit switched networks.
There are some regimes which want video surveillance systems to monitor services like Skype and WhatsApp and threaten to ban their use if they do not. For those who do not know, surveillance monitors behavior, activities or other changing information.
Business telephone systems often use VoiP phone systems. It is for this reason that they will probably become increasingly popular in the future. Whether or not people continue to use voice over ip phone systems is uncertain. There is always the possibility for an alternative to the voice over IP phone systems to develop just as it developed as an alternative to other systems.
However, for the moment Voice over IP phone systems will probably remain popular. They have not had their share of disrupting the system just yet and they likely have a long way to go before the technology has become as disruptive as it possibly can be.
It is uncertain at this point whether the Voice over IP systems can disrupt totalitarian regimes in the ways that many totalitarian regimes fear that they will. Nonetheless, for the time being they will probably remain cutting edge enough to make a lot of people nervous. They could also hasten the prolific nature of telecommuting. About ten percent of American workers work from home, and this might only increase as voice over systems increase immediacy. One thing is for certain, this is the kind of technology that is changing he world as we know it. Great references here.
