v. t. e. The Session Initiation Protocol (SIP) is a signaling protocol used for initiating, maintaining, and terminating communication sessions that include voice, video and messaging applications. [1] SIP is used in Internet telephony, in private IP telephone systems, as well as mobile phone calling over LTE (VoLTE).
The Session Initiation Protocol (SIP) is a signaling protocol used for controlling communication sessions such as Voice over IP telephone calls. SIP is based on request/response transactions, in a similar manner to the Hypertext Transfer Protocol (HTTP).
RTP payload formats. The Real-time Transport Protocol (RTP) specifies a general-purpose data format and network protocol for transmitting digital media streams on Internet Protocol (IP) networks. The details of media encoding, such as signal sampling rate, frame size and timing, are specified in an RTP payload format.
H.323. H.323 is a recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. [ 1 ] The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point ...
t. e. The Session Description Protocol (SDP) is a format for describing multimedia communication sessions for the purposes of announcement and invitation. [1] Its predominant use is in support of streaming media applications, such as voice over IP (VoIP) and video conferencing. SDP does not deliver any media streams itself but is used between ...
A codec is a device or computer program that encodes or decodes a data stream or signal. [1][2][3] Codec is a portmanteau of coder/decoder. [4] In electronic communications, an endec is a device that acts as both an encoder and a decoder on a signal or data stream, [5] and hence is a type of codec. Endec is a portmanteau of encoder/decoder.
The Standard Interchange Protocol is a proprietary standard for communication between library computer systems and self-service circulation terminals. Although owned and controlled by 3M, the protocol is published and is widely used by other vendors. [1] Version 2.0 of the protocol, known as "SIP2", is a de facto standard for library self ...
The Session Initiation Protocol (SIP) is the signaling protocol selected by the 3rd Generation Partnership Project (3GPP) [1][2] to create and control multimedia sessions with multiple participants in the IP Multimedia Subsystem (IMS). It is therefore a key element in the IMS framework. SIP was developed by the Internet Engineering Task Force ...
