What Is a Softswitch?
In Voice over Internet Protocols (VoIP) networks or Time-Division Multiplex (TDM) networks, a softswitch is a software-based switching solution used to make, maintain, route, and end either call or streaming sessions. A softswitch uses software on standard hardware to control calls or streaming, rather than dedicated switching hardware. For network infrastructure using all-IP and only VoIP calls, a softswitch can be virtualized and run on general-purpose hardware with Ethernet connections.
