VoIP protocols

1. Networks.VoIP make it easier to communicate interconnection protocols VoIP (voice over Internet Protocol) is a voice/data communications technology, computer and telephone interconnect networks (and communication) to global between you.

This technology (such as other electronic communication technologies) requires that certain provisions and procedures standard (or protocols) perform its regularized manner. VoIP protocols define the architecture of their respective networks, primarily with the commands used to start and stop a session within the video / audio communications. Multiple protocols are designed and implemented VoIP networks (since its first commercial development in 1995) and just a few of you remain accepted around the world.

H. 323

H. the oldest and the most common implemented VoIP, developed by the International Telecommunication Union (ITU) Protocol, 1995-1996 is 323.

This is actually a suite of protocols, i.e. a log that contains several subprotocols it to perform various operations. The most important protocols listed in h. 323 RTP (real time-transfer protocol) include (digital video broadcasting) and h. 245, 225, DVB. These protocols operate initiation and the session necessary, a VoIP network. H. deploying VoIP is 323 network architecture ever first commercial credited. This architecture contains terminals (end-user), several units control (control terminals for connecting), gateway (for external network communications) and the guardians of the gate (to control operations)(des_Gateways).

SIP

SIP (Session Initiation Protocol) is a protocol for VoIP

and designed by the IETF (Internet Engineering)-working group. This Protocol was developed in 1996 and released to the public in 1999 (i.e. three Yoreilles after h. 323). SIP is a possible, more versatile than its counterpart is h.323 protocol, since its foundations using HTTP (Hypertext Transfer Protocol), often called the backbone of the Internet Protocol. Protocol (SIP) consists of a VoIP network, contains only two main groups of elements model: servers and clients. Server manage network connections, Internet communications, billing issues and many other operations, work that customers simply generate applications to communicate with other clients. In this SIP provides some standard, unique commands (for clients), served on SIP VoIP networks worldwide.

H. 248 (MEGACO)

H. 248 (or MEGACO) is a joint development of two global communications regulators: the ITU and IETF.

In contrast to the h. 323 and SIP h. 248 is a signalling Protocol which means first and foremost, it is not used for voice and video between customers VoIP; Network data sharing instead it embeds, to provide the carrier signal to support this process for exchanging data. In a normal Assembly VoIP h. 248 is used to control and Commander portals that by signal actively connected. H. 248 is also used as a protocol for signaling between country phone and VoIP networks (rarely).

MGCP

MGCP (Media Gateway Control Protocol) is a further signali

Using you control VoIP protocol used to control external media gateways. External media gateways are intermediate points of interconnection between the two to two verschiedenen networks (such as telephone network and VoIP, VoIP network and computer) belong to. MGCP is appointed a signaling protocol a network with a single media gateway control location, the Board (Media Gateway controller) architecture offers. It is here that all commands and MGCP (for the control of media gateways) signals and ResponsableEd.
