Software based telephone call handler Essentially it is like a mini and software version of a telephone exchange. It handles the paths and routes the telephone calls to their destinations and facilitates calls. Some superior soft-switches like Transcom's SCO also manage LCR's and construct Billing records.
Generic term for any open application program interface (API) software used to bridge a public switched telephone network and voice over Internet protocol by separating the call control functions of a phone call from the media gateway (transport layer).
A softswitch is a programmable network switch that processes signals for all kinds of packet protocols. Also known as a "Media Gateway Controller", "Call Server" or "Call Agent". It is a software that resides on fault-tolerant servers and performs call control functions such as protocol conversion, authorization, accounting and administration operations. Traditionally, voice-switching applications have been proprietary software running on Class 4 and Class 5 hardware. That has typically meant big waits for service providers that wanted new applications to differentiate their services. In a softswitch, solutions can come from multiple vendors, at all levels who supply open standards-based products and customers are free to choose best-in-class products to build their network. Open standards enable innovation and reduce costs.
