Multiple Choice

This type of UC component is the call control system that handles the primary call routing and connections between IP phones.

The main idea being tested is which UC component acts as the central call control system, coordinating signaling and routing between IP phones. The UC Server fits this role because it handles the call signaling, sets up and tears down connections, and applies features and policies across endpoints. It’s the element that determines the path of a call and connects the participating IP phones. The other components don’t serve that internal call-control function. A UC Gateway connects the UC system to external networks (such as the PSTN or other domains) and handles protocol conversion and media bridging, not internal call routing between IP phones. A UC Device is an endpoint itself, like an IP phone or soft client, which initiates and receives calls but relies on the server for signaling and control. A UC Router deals with network-level packet routing and QoS, rather than managing call signaling and connections. So, the UC Server is the component responsible for the primary call routing and connections between IP phones.
