OneAgentWeb can initiate and receive video calls, and video-extend an ongoing call. The dial video button is visible only if your computer has a video camera.
You have the possibility of seeing both the remote an local video streams. The local image is typically smaller, and visible even before the call is connected. The remote image appears only once the call is connected.
The video windows is shown in the sidebar, inside the interaction tab (see below). When dialing an outbound video call, or before accepting an inbound video call, the video tab shows the local video image. After the call is connected, the remote video is shown and the local video is shrunk to the lower right corner. During the call, you have the option to hide/show the local video image at any time. The video window can be popped out to allow re-sizing.
Note: OneAgentWeb disables the webcam when not needed (in Google Chrome).
