Enhanced VoIP by Softswitch

The cost-effective VoIP solution is promoting the development of core voice networks from traditional circuit switching to SoftSwitch.
In the next generation telecommunication network, through the media gateway and media gateway Controller Based on Softswitch, direct voice communication between the traditional voice network and the packet switching network can be realized.
In this new type of hybrid communication network, some network units logically separated from each other will appear, such as the media gateway, signal processing gateway, media gateway controller, and application server, they communicate with each other through the internal protocols of the switch, such as media gateway control, gateway control protocol, and initial session protocol.
The most basic function of Softswitch is to provide call control and resource management functions for media gateway.
The call control relationship refers to the entire process from the establishment of a call to the revocation, including the location where the call is established by a call route and where the call is sent) and whether the service is a common call service or other value-added services ). By accessing the relevant information from the SS7 network, Softswitch can simultaneously provide call authentication, authorize the types of calls allowed by specific lines) and accounting services.
SS7 signaling interfaces can communicate with SS7 networks. They are sometimes divided into independent hardware, called Signaling gateways.
