Which UC component connects the Voice over IP system to the Public Switched Telephone Network?

Connecting Voice over IP to the Public Switched Telephone Network requires a bridge that handles interworking between IP-based voice and the traditional circuit-switched network. A UC Gateway performs this role, translating signaling and media so calls can move between the VoIP system and PSTN (for example, converting SIP to PSTN signaling and handling any necessary transcoding or protocol adaptation). This gateway is the mechanism that actually connects the two different networks. The other components don’t serve this bridging function: a UC Device is an endpoint for users, a UC Router focuses on IP packet routing, and a UC Server provides UC services but is not the network interconnection to the PSTN.
