Enable Video Preview of Intercom Calls for Extensions
If you integrate video intercom system with Cloud Voice, you can enable video preview of intercom calls for the extension registered on the door station. In this way, when receiving an incoming call from the door station, users who have their extensions registered as the indoor station can preview the visitor's video on their Cloud Voice App UC clients while ringing, and control the opening of the door.
Scenario
A video intercom system contains a door station and an indoor station. If you integrate video intercom system with Cloud Voice, you can make the door station a regular PBX extension for making calls by registering an extension on it, and Cloud Voice App UC clients can work as the indoor station.
When visitors press the door station to ring the bell, the door station sends the doorbell (namely a call) to the indoor station. Users can preview the video on Cloud Voice App client while ringing, and decide whether to open the door for visitors.

Methods of previewing videos
Cloud Voice supports the following two methods of previewing videos:
- Video Preview: This method requires action from callee. When receiving an incoming call from door station (with video preview enabled on the extension), the callee can click the preview button on the Cloud Voice App client to preview the video while ringing.
- Auto Preview: This method does NOT require action from callee. When receiving an incoming call from door station (with auto preview enabled on the extension), the callee's Cloud Voice App client will automatically show the video while ringing.
