VoIP: The Next Generation Communication Standard

In this age of digitization, everything we view or hear has some or all part of it digitized, which is in the interest of better quality and efficiency. Data and voice communication is no exception to this, and therefore, is presented to the users in digital form through VoIP services. Gone are the days, when long distance calls used to cost a bomb on those traditional phone services. Now users can not only make international calls at the price of local calls, but can also be assured of superior voice clarity, whatever be the distance and conditions. Furthermore, there are a number of online VoIP reviews, which can guide you to the best and the most appropriate service provider for providing these services.

Voice over Internet protocol is a convergence of Internet technologies, communication protocols and transmission technologies, which is used for delivery of voice and multimedia data over the IP network. Also referred to as voice over broad band (VoBB), this technology involves various processes such as signaling, digitization of the analog voice signal, encoding, packetization and transmission over a packet switched network. Similar steps are followed on the receiver side in the reverse order. These systems work on the basis of session initiation protocol, which regulates the setup and tear-down of calls along with audio codec. This application layer protocol has been designed to work independently of the successive transport layers, insulated from them. They can run on various protocols such as TCP, UDP and SCTP. Working in conjunction with all these protocols, SIP is involved in signaling part of a communication session.

VoIP services primarily work on well defined methodologies, which involve sending packed digitized data over the internet. The packets comprise a header (which contains information about the source as well as destination) and a payload, which is the information being transferred. In traditional phone service or PSTN line one usually pays as per the real time usage. It effectively translates into higher telephone utility bill for more time spent talking. This is where VoIP proves a clear winner as it provides the facility to talk as much as needed & the only bill one has to pay is regular internet bill which has to be paid any way to the internet service provider. Another advantage people enjoy while using this cutting edge solution is that they can talk with as many people, who are connected to the internet, simultaneously, as they want, without paying anything extra. Everyone can savor these benefits by checking for the best service provider on various online VoIP reviews and choosing the one, which fulfills their conditions and requirements.
