VoIP is a technology that sends voice over package networks. Earlier, people used PSTN networks and mobile networks to communicate with each other. The rapid growth of the Internet and network technology has introduced voice into data networks with carrier-grade quality. In simple terms, VoIP means to make calls or to receive telephone calls over the web or an internal system as apart of telecommunications service provider singapore.
SIP which is Session Initiation Protocol is an application covering strategy that allows the installation, modification, and abandonment of various media sessions, such as VoIP calls. SIPs can also invite new sessions to existing sessions such as multicast conferences, basically referred to as signal protocols in a VoIP environment that can create call detail recordsfor call establishment, call control and call termination and billing purposes.
Observation Procedures in the Work of Telecommunication Systems Using VoIP
- Transmission Control Protocol
The transmission control protocol is a protocol that maintains the reliability of end-to-end communication links. The basic concept of how TCP works is, sending and receiving segments of information using various lengths of data, on an internet datagram. In conjunction with VoIP, TCP is usually used to set up a call in a signalling session. So TCP is not used to transmit voice data, because in VoIP data communication, handling delayed data is more important than handling lost packets.
- User Data Protocol
The user data protocol is one of the main protocols above IP, which is simpler than TCP. This one protocol is usually used in situations where reliability mechanisms are not important. UDP in VoIP is used for sending audio streaming that takes place continuously and is more concerned with the speed of data transmission.
- Internet Protocol
The Internet Protocol is designed to interconnect computer communication systems on a packet switched networks. On an IP/TCP network, a computer is identified by an IP address. So each computer has an IP address that is unique and different from one another. Finally, the accent data protocol is directly connected to the physical media.
