A router, in the context of telephony, refers to a device that manages the flow of voice and data traffic across multiple networks. It serves as the central hub for connecting various telephony devices and networks, enabling seamless communication between users.
The primary function of a router in a telephone system is to direct incoming and outgoing calls to their intended destinations. It determines the most efficient path for call routing based on predefined rules and configurations. Routers also facilitate call routing between different types of networks, such as landlines, mobile networks, and VoIP systems.
