Typical Deployment Scenarios

The combination of platform, boundary, and endpoint depends on the existing relay type, extension scale, and whether call recording is required. Refer to the following four scenarios to find your fit.

Enterprise Office Communication

The UC series IP PBX handles extension registration and call routing, connects to carrier E1 or SIP trunks via gateway, and supports desk phones and softphones across all roles.

Hotels & Apartments

The UC platform's integrated hotel management system interfaces with the call center, allowing guest room phones and front desk agents to share a single number and billing rules.

Call Center Agent

The SBC handles relay access and security protection. The recording system archives data in real time. G-series color screen handsets and expansion units are configured according to seat scale.

Park and Intercom Access

SIP intercom terminals are deployed at entrances, elevators, and patient rooms. They receive PoE power and connect to the UC platform for call routing.
