Voice Over Internet Protocol

The future of the telephone industry is under a threat because of what VoIP had introduced into the market place. The introduction had made making phone calls very cheap when compared with what customers are getting using the Public Switch Telephone Network (PSTN). There are even cases where phone calls can be made for free, not only in a given locality but nation wide, from one state to the other, and globally.

What this means is, in the near future, phone companies will cease charging their customers for voice telephone service as everyone will be able to make a phone call from a PC. It takes only installing software that are being offered by various sources, free in some cases, and a mike and an earphone to empower a PC to do the whole job. Alternatively, it is possible to use an analog adapter by plugging a conventional telephone into it or what are known as IP phones that are directly connected to a router could also be used to avail the service. The IP phone comes with a software and the equipment is capable of making telephone calls. It is not only that VoIP is offering a very low-cost telephone service.

VoIP service had been possible because of the capability that came into existence when converting analog into a digital form was possible. The converted digital analog could be changed into a package that could be send through an Internet connection and it will be received by another converter at the other end that will convert it back into analog, the final form that will reach the receiver at the other end.
