Elegnat Softech Developed telecommunications network solutions which connects telephone calls from one phone line to another, entirely by means of software running on a computer system. This work was formerly carried out by hardware, with physical switchboards to route the calls.
The Call Agent takes care of functions including billing, call routing, signalling, call services and so on and is the ‘brains’ of the outfit. A Call Agent may control several different Media Gateways in geographically dispersed areas over a TCP/IP link.
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.
