Softswitch Wikipedia. A softswitch software switch is a central device in a telecommunications network which connects telephone calls from one phone line to another, across a telecommunication network or the public Internet, entirely by means of software running on a general purpose computer system. Most landline calls are routed by purpose built electronic hardware however, soft switches using general purpose servers and Vo. IP technology are becoming more popular. Many telecommunications networks now make use of combinations of softswitches and more traditional purpose built hardware. Although the term softswitch technically refers to any such device, it is more conventionally applied to a device that handles IP to IP phone calls, while the phrase access server or media gateway is used to refer to devices that either originate or terminate traditional land line hard wired phone calls. In practice, such devices can often do both. Window 7 Activator Torrent File on this page. As a practical distinction, a Skype to Skype phone call is entirely IP internet based, and so uses a softswitch somewhere in the middle connecting the calling party with the called party. In contrast, access servers might take a mobile call or a call originating from a traditional phone line, convert it to IP traffic, then send it over the internet to another such device, which terminates the call by reversing the process and converting the Voice over IP call back to older circuit switched digital systems using traditional digital ISDN PSTN protocols that transmit voice traffic using non IP systems. A softswitch is typically used to control connections at the junction point between circuit switched and packet switched networks. A single device containing both the switching logic and the switched fabric can be used for this purpose however, modern technology has led to a preference for decomposing this device into a Call Agent and a Media Gateway. The Call Agent takes care of functions such as billing, call routing, signaling, call services and the like, supplying the functional logic to accomplish these telephony meta tasks.

Voip Softswitch Software' title='Voip Softswitch Software' />A call agent may control several different media gateways in geographically dispersed areas via a TCPIP link. It is also used to control the functions of media gateway, in order to connect with media as well as other interfaces. This procedure is utilized to keep the interfaces clear as crystal for receiving calls from any phone lines. The media gateway connects different types of digital media stream together to create an end to end path for the media voice and data in the call. It may have interfaces to connect to traditional PSTN networks, such as DS1 or DS3 ports E1 or STM1 in the case of non US networks. It may also have interfaces to connect to ATM and IP networks, and the most modern systems will have Ethernet interfaces to connect Vo. IP calls. The call agent will instruct the media gateway to connect media streams between these interfaces to connect the call all transparently to the end users. The softswitch generally resides in a building owned by the telephone company called a telephone exchange UKIRLAUSNZ or central office USCAN. The central office or telephone exchange has high capacity connections to carry calls to other offices owned by the telecommunication company and to other telecommunication companies via the PSTN. Looking towards the end users from the switch, the softswitch may be connected to several access devices via TCPIP network. These access devices can range from small Analog Telephone Adaptors ATA which provide just one RJ1. Integrated Access Device IAD, e. MTA s embedded Multimedia Terminal Adapters using MGCPNCS protocol over cable Vo. Cable or PBX which may provide several hundred telephone connections. Note here that Analogue ATA, PSTN telephone devices can only be reached by a softswitch that has embedded SS7 or SIGTRAN cards, software in terms of signalling AND Trunking Gateway for Voice traffic IPTDM, TDMIP, TDMTDM functions. Typically the larger access devices will be located in a building owned by the telecommunication company near to the customers they serve. Each end user can be connected to the IAD by a simple pair of copper wires. The medium sized devices and PBXs are most commonly used by business that locate them on their own premises, and single line devices are mostly found at private residences. At the turn of the 2. IP Multimedia Subsystem or IMS, the Softswitch element is represented by the Media Gateway Controller MGC element, and the term Softswitch is rarely used in the IMS context. Rather, it is called an AGCF Access Gateway Control Function. Feature servereditThe feature server, often built into a call agentsoftswitch, is the functional component that provides call related features. Capabilities such as call forwarding, call waiting, last call return and three way videoconferencing, if implemented in the network, are implemented in the feature server. The feature server works closely with the call agent, and may call upon the media server to provide these services. These features do not require the subscriber to explicitly request them but tend to be triggered within the call handling logic. Class 4 and Class 5 softswitcheseditVo. Winning Eleven 7 International Patch'>Winning Eleven 7 International Patch. IP softswitches are subdivided into two classes Class 4 and Class 5 softswitches, in analogy to the traditional functions in public switched telephone network. Softswitches used for transit Vo. IP traffic between carriers are usually called class 4 softswitches. Analogous with other Class 4 telephone switches, the main function of the class 4 softswitch is the routing of large volumes of long distance Vo. IP calls. The most important characteristics of class 4 softswitch are protocol support and conversion, transcoding, calls per second rate, average time of one call routing, number of concurrent calls. Class 5 softswitches are intended for work with end users. These softswitches are both for local and long distance telephony services. Class 5 softswitches are characterized by additional services for end users and corporate clients such as IP PBX features, call center services, calling card platform, types of authorization, Qo. S, Business Groups and other features similar to other Class 5 telephone switches. Hosted switch serviceseditDue to the high costs of infrastructure and its maintenance, some softswitch solutions are offered through a hosted service provider model. Users rely on softswitch infrastructure managed by a third party to deliver services to their end users without owning or operating their own softswitch. See alsoeditReferencesedit.
