How it is work? In the first step, the voice of the caller is digitized, since in VoIP all transmissions must be digital. This digitization can be performed either by the telephone company, or by an Internet Service Provider -ISP, or by a Personal Computer. In the second step, using intricate algorithms, the digital voice is compressed and then divided into packets; and utilizing the Internet protocol, the packets are addressed and transmitted through the network to be reassembled in the right order at the destination point. Once again this task of reassembling can be carried out by a carrier and Internet Service Provider (ISP) or by the PC. In the third step, while in transit in the Internet, the data packets might be lost or delayed, or errors might cause damage to the packets. Conventional methods of error correction will request retransmission of unusable or lost packets, however, in the case of the sound which is sent as a real-time voice communication, that technique will not be functional, hence sophisticated error detection and corrective systems are employed to create sound to fill in the dropouts in sounds
I would say VoIP will influence the communication sector in the future years as the number of subscriber in broadband internet service increased year by year. The numbers of VoIP providers are increased and they will offer many option to the user regarding the using feature and cost.
The succeed of VoIP depend in three things First, VoIP providers have to overwhelmingly on price Secondly ,and More important, they also have to match the quality of sound (Oos) . Finally, Independent VoIP providers improved their amenities to come over traditional phone companies
