telecom operators. The IP telephone voice service is the most important and fundamental service function in the soft switch.　　　　2. Softswitch TechnologyThe concept of Soft switch was proposed by Bell Laboratory of longxun in 1997 to integrate the existing traditional PSTN Circuit Switching Network with IP/ATM data network.　　As the control entity of the Next Generation Network, Softswitch provides Call Cont

NextGenerationNetwork (NGN) is a new concept used by the network to describe future telecommunication networks. It is like a big umbrella, covers the fixed network, Internet, mobile network, core network, man, access network, user resident network and many other fields. The evolution of technology has brought about the rapid development of network convergence, telecom business integration, and personalized communication services. As a core technology of NGN,

Broadband ip man-based wireless and IP multi-service access applications The voice service is still the main growth point of profit of domestic operators. While building a broadband MAN to implement data services, it also carries voice services on the established data network to avoid re-laying the cables, so as to achieve the convergence of two network data and voice at a low cost, moving towards triple play will be an inevitable choice for emerging operators.UTSTARCOM's mSwitch

larger share. The current IP communication technology is mainly based on SoftSwitch. The used Signaling Protocols include h323 and SIP (Session Initiation Protocol ). H323 is the main protocol used in early VoIP. But at the end of 1990s, IETF began to develop the SIP protocol. Because of its simplicity, scalability, implementation, and integration of other existing Internet technologies, such as HTTP and Uri, it quickly becomes the mainstream comm

With the rapid development of computer and network technology, call centers are being used by more and more enterprises and organizations to carry out customer service, marketing, technical support and other specific business activities. The stability and security of a call center system of an enterprise and an organization are the image of an enterprise and an organization, which has become the important choice for the call center to ensure the safe operation of the system, prevent the accident

NGN features a complex converged network based on multiple IP technology vendors, multiple technologies, and different architectures. Softswitch plays an extremely important role in controlling such a heterogeneous network. Control is implemented through protocols. The main Protocols involved in implementing Softswitch include H.323, H.248/MEGACO, SIP, SIGTRAN, and BICC. Check five major protocols H.323 Pro

The Softswitch technology is worth learning a lot. Here we mainly introduce the media logical channels in the Softswitch technology. This channel carries H.245 information, which is used for media control with capability exchange support. After the caller completes the capability exchange, he/she creates a media logical channel through this channel. Media Logical Channel This channel carries voice, video, a

When someone asked me what is Softswitch, I directly replied: the network architecture with media gateway is SoftSwitch. Now we can see that a general computer is used as a telephone switch, so it is a soft switch ). It is the same because the control logic is separated from the speech exchange hardware by media gateway, so the control logic (Application Layer) can naturally be implemented by software run

I recently bought a new office building and the telephone system of the new Office, including Softswitch, digital relay gateway, E1 and VoIP, which should be configured by me. Multi-function programmer :) The following are some records during freeswitch configuration. I will share them with you here. For more details, see the official FS and Chinese official website. 1. freeswitch SRC contains a Perl script. add_user adds users in batches. 2. view Use

to MTP3, isup iua corresponds to Q931/QSIG, and ISUP (1) SCTP protocol SCTP proposed by IETF, which is a connection-oriented transport layer protocol, the TCP-like traffic control and congestion control algorithms are used to ensure reliable transmission of user data between two SCTP endpoints through self-validation and re-transmission mechanisms. Compared with other transmission protocols such as TCP, SCTP has a low transmission latency, which can avoid the blocking of some big data on other

With the approaching of 3G, mobile network and fixed network introduce the design idea of softswitch while interpreting the transformation from circuit switching to SoftSwitch, it also represents an important trend-mobile network and fixed network convergence.With the emergence of new communication methods, methods, and services, the communication Network is evolving to a more open and flexible Next Generat

I. Introduction When a call is established for a traditional telephone exchange network, the signaling point code of the next exchange board is determined based on the E.164 number of the called phone number, and then the call is routed through the No. 7 signaling network according to the signaling point code, the essence of all call routes is to determine the signaling point encoding according to E.164, and then use the signaling point encoding for call routing. Unlike the traditional PSTN (Pu

TISPAN standard in the future. NGN should be a network that supports both fixed businesses, nomadic businesses and mobile businesses. The NGN architecture proposed by TISPAN can be connected to both mobile users and fixed users. However, the evolution of the existing fixed network and mobile network to the NGN network will be a gradual process and will follow two completely different paths: the fixed network first evolves to a softswitch network that

The Softswitch technology is quite common, So I studied the application of soft exchange technology in the next generation of networks. Here I will share with you, hoping to be useful to you. As the core technology of the Next Generation Network, Softswitch has become one of the most important topics in the telecom field, whether it is telecom operators, equipment manufacturers, or business developers dedic

Circuit Switching refers to a physical link corresponding to a connection, while the Softswitch technology is a physical link corresponding to multiple virtual connections. The use of soft switches in the intelligent network transformation process is also a direction for the application of Softswitch technology. replacing the traditional exchange board switch with Softs
