Cheap calls around the world

Voice over Internet Protocol (also called VoIP, IP Telephony, Internet telephony or Digital Phone) is a technology that enables voice conversations over long distances through internet media. Voice data is converted into digital code and transmitted over a network that sends data packets, rather than through a regular analog telephone circuitry. Its can beĀ cheap calls around the world.

The definition of VoIP is the voice that is sent over the internet protocol (IP).

Voice over IP has been implemented in a variety of ways using proprietary rights and open standards and protocols. Examples of network protocols used to implement VoIP include:

Media Gateway Control Protocol (MGCP)
Session Initiation Protocol (SIP)
Real-time Transport Protocol (RTP)
Session Description Protocol (SDP)
Inter-Asterisk eXchange (IAX)
The H.323 protocol is one of the widely used VoIP Protocols for long-distance traffic, such as Local Area Network (LAN) services. However, due to new developments, more complex protocols such as MGCP and SIP, H.323 deployment are increasingly limited to carrying long distance existing network traffic. In particular, the Session Initiation Protocol (SIP) has gained widespread market penetration of VoIP.

An important property implementation is the Skype protocol, which is based in part on peer-to-peer (P2P) networking principles.

Comparison with conventional voice network

The simplest form of a VoIP system is two computers connected to the internet. The basic requirements for establishing a VoIP connection are computers connected to the internet, having a sound card connected to speakers and microphones. With the support of specialized software, both computer users can connect to each other in VoIP connections with each other.
