As more and more businesses make the move to IP, VoIP networks are becoming an important element for enabling real-time communications.

This move involves transforming the PSTN to support voice, data and video capabilities via a packet-switched network instead of using hardware and routing switchboards.

Not only does this bring cost savings and advanced capabilities, but also, a large amount of data now finds its way on the IP network.

Serving as a "mediator" for all of the different traffic flowing through the network is the VoIP Softswitch.

The VoIP Softswitch connects calls using software that runs on a computer system.

The VoIP Softswitch not only routes and translates all the different traffic and clears a path across the network, but it also offers authentication and authorization.

Because the VoIP Softswitch brings voice and data together onto a single network, and allows only signaling to go through the Softswitch, the VoIP Softswitch costs less and uses bandwidth more efficiently.

Maintenance costs are also reduced with the VoIP Softswitch, and power and space in the host office are also decreased.

With the VoIP Softswitch, which is modular, it is possible to roll out and create new services more easily, depending on the changing needs of the market.

VoIP Softswitch provider, Dialexia, offers Dial-Gate, a Web-based softswitch that translates standard telephone numbers into corresponding IP addresses and looks for available gateways or domains to place calls through the PSTN. It functions as a softswitch by giving an integrated control point for various telephony services.

Since many companies are making their way to all IP networks, the VoIP Softswitch is increasingly becoming a necessity to achieve cost efficiency and improve business.
