VoIP i.e. Voice over Internet Protocol is known as IP telephony. It is the combination of a group of technologies and methods for the transmission of voice communications and multimedia files through the IP network, such as the internet. IP telephony uses VoIP systems rather than traditional Public Switched Telephone Network for transferring the communication services like voice, SMS, fax, voice-message. These methods are required for generating VoIP telephone calls and are more or less similar to the traditional digital phone calls, digitization of analog signals and channel setup.

How does a VoIP system work?
Digitals phone calls or information are generated as a form of IP packets and the transmission occurs over the packet-switched network instead of a circuit-switched network. For the transmission of the multimedia sessions, special media transmitting protocol is used that encode the audio and the video streams. As VoIP systems are working with different internet technologies, it has the advantage of being used in multiple numbers of internet-supported devices. So, VoIP systems can be used in a desktop, mobile phones, various MAC machines. By using VoIP calling systems you can able to make calls across the local area network (LAN) and wide area network (WAN). The main technology of the VoIP network is that it converts the analog voice signals to the digital packet which ultimately send to the end destination by the internet protocol (IP).
Local area network (LAN) works as the backbone of the VoIP systems. IP telephony is used by the VoIP systems to control the voice calls and handle your connections to the wide area network (WAN). You can connect VoIP calling systems with VoIP and well as directly to PSTN to get both VoIP and PSTN calling service.
