Integrated voice features, for example, integrated messaging and click-to-dial, became available for the cycle-switched PBX systems. Complex coordination of voice and data network environment is required. IP network level, however, much of this complexity, the land, which is the result of low cost materials and strengthen the cooperation and business applications quickly. Requirements for IP PBX systems integration and network packet success is:

oReliability reduce network losses and the voice packet delay control.

oQuality Service (QoS) to ensure that the voice packets transmitted through the network and the relative priority of each aspect of the right kind of package.

Real Time Protocol (RTP)

RTP uses a set of Internet Engineering Task Force (IETF) standard protocol for reliable transport voice, video, and data sharing between the parties in the packet network. Comments and requests:

Othe RTP protocol (RFC 2550), which has brought the sound or encoded using the ITU G.711 Codec alternative system. Protocol includes the time stamp and sequence number, material management.

oRTP for dual tone multi-frequency coded with numbers tons used in interactive voice response (IVR) applications.

oRTP Redundant audio data for a particular mode of transportation equivalent audio sequencing pattern to effectively reduce the number of packets transmitted diseases.

H.323

H.323 - ITU-related series of recommendations that describe the design of multimedia communications over packet-switching network. Key factors:

Oh. 323, Participation Multimedia infrastructure, including the role of equipment, gateway and gatekeeper.

Oh. 245, call control to set inayobainisha process and Multimedia session, which includes hand and power sharing client device.

Oh. 450, inayobainisha set of additional equipment, such as call transfer, hold, etc. waiting for an important message of this protocol for communication between clients without the help of the change.

Session Initiation Protocol (SIP)

SIP is the IETF standard protocol support to establish an interactive user session that brings Multimedia lessons. SIP architecture and how to come to service connection for users at every place where he is registered. Unlike H.323, SIP extensible using text-based format, similar to HTTP. SIP, a basic program used with instant messaging Gaming. Can work as a call control protocol or Standalone with H. 323.
