Payload Type: The payload type is used to indicate, on a per-packet basis, which format is used. The binding between a payload type number and a payload format and its configuration are dynamically bound and RTP session specific.
1 : the load carried by a vehicle exclusive of what is necessary for its operation especially : the load carried by an aircraft or spacecraft consisting of things (such as passengers or instruments) necessary to the purpose of the flight. 2 : the weight of a payload.
In computing, a payload is the carrying capacity of a packet or other transmission data unit. In the context of malware, the payload usually refers to malicious code that causes harm to the targeted victim.
In computer networking and telecommunications, when a transmission unit is sent from the source to the destination, it contains both a header and the actual data to be transmitted. This actual data is called the payload. The payload is required by the destination client.
SAVPF Rules SAVP is defined as an intermediate layer between RTP (following the regular RTP profile AVP) and the transport layer (usually UDP). This yields a two-layer hierarchy within the Real-time Transport Protocol. In SAVPF, the upper (AVP) layer is replaced by the extended RTP profile for feedback (AVPF).
Payload Type: MPV designates the use MPEG-I and MPEG-II video encoding elementary[5]. This value is assigned 32 for video elementary stream.
The Payload of an API Module is the body of your request and response message. It contains the data that you send to the server when you make an API request. You can send and receive Payload in different formats, for instance JSON.
Comfort noise (or comfort tone) is synthetic background noise used in radio and wireless communications to fill the artificial silence in a transmission resulting from voice activity detection or from the audio clarity of modern digital lines.
The Session Description Protocol (SDP) is a format for describing multimedia communication sessions for the purposes of announcement and invitation. Its predominant use is in support of streaming media applications, such as voice over IP (VoIP) and video conferencing.
The role of RTP is to ensure a uniform way to transmit data subject to real-time constraints. For this purpose, RTP injects time markers and sequence numbers to the various multimedia streams (audio, video, etc.), controls the destination arrival of the packets, and identifies the type of information transported.

These lines specify G711 mu and a-law, which is telecom's classic 64kbps pulse code modulation (PCM) codec using different companding laws. 0 and 8 are the static payload types for PCMU and PCMA respectively.
Explanation: RTP stands for Real-time transport protocol and is for delivering audio and video over IP networks. Its applications include streaming media, video teleconference, and television services. Explanation: RTP is used to carry the media stream for delivering audio and video over IP networks.
PCMU is PCM using μ-law, which is popularly used in North America. PCMA is PCM compression using the A-law scheme used in Europe and some countries of Asia. The basic difference between PCMU and PCMA [URL (PCM), URL (TI-PCM)] schemes are actual quantization, coding steps, dynamic range, and bit formats.
A codec based on the H. 264 standard compresses a digital video file (or stream) so that it only requires half of the storage space (or network bandwidth) of MPEG-2. Through this compression, the codec is able to maintain the same video quality despite using only half of the storage space.
RTCP stands for Real-time Transport Control Protocol and is defined in RFC 3550. RTP does the delivery of the actual data, whereas RTCP is used to send control packets to participants in a call. The primary function is to provide feedback on the quality of service being provided by RTP.
711 is a narrowband audio codec originally designed for use in telephony that provides toll-quality audio at 64 kbit/s. 711 is an ITU-T standard (Recommendation) for audio companding, titled Pulse code modulation (PCM) of voice frequencies released for use in 1972.
The DTMF Payload Type Number is the RTP Payload Type Number that indicates the transmitted packet contains DTMF digits. The dialed digit is encoded as an NTE (Named Telephone Event). As specified in RFC 2833, RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals, each dialed digit has a unique NTE.
H. 323 is, much like SIP (Session Initiation Protocol), a protocol designed for the setup, management, and termination of a media session. It is one of a set of standards from the ITU-T, which defines a large set of protocols to provide audio and visual communication over a computer network.
In the context of RTP , an RTP payload type is a 7-bit numeric identifier that identifies a payload format. For payload types, GNU ccRTP defines the integer type PayloadType . Codes in the range 96-127 are assigned dinamically by means outside of the RTP profile or protocol specification.
Both endpoints i.e. IP phones or mobile's involved in the phone conversation must agree which codec is going to be used for a particular call in order to ensure interoperability and correct decoding of the audio sent. This process is called Codec negotiation and occurs while the SIP signalling is setting up the call.
SDP stands for Session Description Protocol. It is used to describe multimedia sessions in a format understood by the participants over a network. SDP is generally contained in the body part of Session Initiation Protocol popularly called SIP. SDP is defined in RFC 2327.
What is SIP? The Session Initiation Protocol is a signaling protocol that enables the Voice Over Internet Protocol (VoIP) by defining the messages sent between endpoints and managing the actual elements of a call. SIP supports voice calls, video conferencing, instant messaging, and media distribution.
