What is Softswitch?

When someone asked me what is Softswitch, I directly replied: the network architecture with media gateway is SoftSwitch.

Now we can see that a general computer is used as a telephone switch, so it is a soft switch ).

It is the same because the control logic is separated from the speech exchange hardware by media gateway, so the control logic (Application Layer) can naturally be implemented by software running on a general computer. The soft switch is the machine that uses Megaco to control the media gateway. If there is a sip, it is also a SIP server. Of course, when there is no media gateway, the soft switch can also exist, that is, when the network is full IP address :) (thousands of miles)
