As mentioned in the previous article VoIP technology allows you to send digital voice packets through the IP network, i.e. through the Internet connection.
Due to the structure of the protocol used for this purpose, it is possible to achieve almost total convergence in communications, as through a unique network is now possible to transmit different types of digital communication packages, such as voice.
Due to the possibilities offered by the use of such technology, the VoIP reports a lot of advantages for users requiring constant communication, beyond the place where they are.
Which are the main advantages of this technology?
Note that one of the main benefits of implementing VoIP technology for communications lies in the significant reduction in operating costs. Through the use of VoIP, it is possible to avoid the high costs of telephony, especially in cases of companies implementing business strategies of Call Centers, or even for users who often make long distance calls. Usually the calls made between different VoIP devices are free, while users established between VoIP and PSTN (Public Switched Telephone Network) must be paid by the first, but at greatly reduced costs, up to 50 times less than conventional communications through local operators.
Moreover, with technological advancement and computer within the scope of the codecs for VoIP at present it is possible to communicate through reduced bandwidths, as digital voice packets are typically smaller and smaller, so that travel at higher speed. For these reasons, communication via VoIP technology is being increasingly used for international calls, due to their low cost of operation.
VoIP phones can be used anywhere in the world, meaning that even though the user is traveling outside their country of origin, you can continue using the service under the same parameters and the same rates, provided they can establish Internet connection.
Another big advantages to using VoIP technology is the ability to communicate the type of conference, which may involve more than one user simultaneously. More services should be noted that applications using and special services, such as the popular Skype, VoIP technology also allows integrating other communication services such as instant messaging, email and video conferencing.
Disadvantages of VoIP
Like any other technology, VoIP architecture also poses certain flaws that call into question their integrity in the eyes of the users who want to incorporate this new method of communication. Delays and / or cuts during a call via VoIP can reach occur late arrival of packets or even cuts information, although it is important to note that this only happens because of the restrictions that many companies that offer the service can get to put in your application, according to the service you have contracted.
Another negative aspect in communication through VoIP technology is the possible deterioration of the communication to be received by the user. Generally this occurs when there is significant congestion on the network or when you use a low bandwidth that allows access to an appropriate speed of connection.
