Which type of protocol is MGCP?

Which type of protocol is MGCP?

MGCP is a text-based protocol consisting of commands and responses. It uses the Session Description Protocol (SDP) for specifying and negotiating the media streams to be transmitted in a call session and the Real-time Transport Protocol (RTP) for framing the media streams.

What does MGCP mean?

Media Gateway Control Protocol
Media Gateway Control Protocol (MGCP), commonly known as H. 248, is a standard protocol for handling the signaling and session management needed during a multimedia conference.

What is H 248 used for?

248. The Gateway Control Protocol (Megaco, H. 248) is an implementation of the media gateway control protocol architecture for providing telecommunication services across a converged internetwork consisting of the traditional public switched telephone network (PSTN) and modern packet networks, such as the Internet.


Media Gateway Control Protocol (MGCP) TCP, UDP: MGCP uses TCP or UDP as its transport protocol. The well known port for MGCP gateway traffic is 2427. The well known port for MGCP callagent traffic is 2727.

What is the difference between h323 and MGCP?

H. 323 is an ITU umbrella recommendation for multimedia communications over IP-based networks that do not provide a guaranteed quality of service. However, compared to MGCP, H. 323 requires more configuration on the gateway since the gateway must maintain the dial plan and route patterns.

What is h323 protocol?

Recommendation H. 323 is a set of protocols for voice, video, and data conferencing over packet-based networks such as the Internet. The current recommendation, known as version 2.0, was ratified by the Study Group 16 (SG16) of the Telecommunications Sector of the International Telecommunication Union (ITU-T). The H.

What is Mgw in telecom?

A media gateway is a device used in the core network of a telecom network operator to provide transformation and interworking between media streams that use different network standards, communication protocols, codecs and physical connections, so that phone calls work properly between networks using different …

What is difference between SIP and MGCP?

Session initiation protocol (SIP) is the next generation protocol of H. 323 it is developed by Internet Engineering Task Force (IETF). Media gateway control protocol (MGCP) – is the client/server VOIP signaling protocol. Majority of gateway configuration is done in MGCP on what is called as call agent.

What is the difference between SIP and h323 protocol?

H. 323 fully supports video and data conferencing. Procedures are in place to provide control for the conference as well as lip synchronization of audio and video streams. SIP has limited support for video and no support for data conferencing protocols like T.

What’s the difference between MEGACO and MGCP?

MGCP and Megaco/H.248 are the Media Gateway Control Protocols defined by the IETF and ITU-T for use in distributed switching environments. (Megaco and H.248 are equivalent names for the same protocol, developed jointly between the IETF and the ITU-T; Megaco is the IETF name and H.248 is the ITU-T name.)

What is the media gateway control protocol ( MGCP )?

The Media Gateway Control Protocol ( MGCP) is a signaling and call control communications protocol used in voice over IP (VoIP) telecommunication systems. It implements the media gateway control protocol architecture for controlling media gateways connected to the public switched telephone network (PSTN).

Is the megaco / H.248 protocol the same as MGCP?

The Megaco/H.248 protocol was developed from the MGCP Media Gateway Control Protocol. It provides broadly equivalent functionality and has a very similar structure. DC-MGCP and DC-Megaco/H.248 provide complete, scalable, and fault-tolerant source code implementations of the MGCP and Megaco/H.248 protocols.

What does the MGCP stand for in VoIP?

The protocol represents a decomposition of other VoIP models, such as H.323 and the Session Initiation Protocol (SIP), in which the endpoint devices of a call have higher levels of signaling intelligence. MGCP is a text-based protocol consisting of commands and responses.
