Question: Why is there no video?
Answer:

First, please check if the video is disabled during the call on both parties. Secondly, please check the angle of the camera on the phone. If the camera lens is adjusted to the highest angle, the video will be disabled. Lastly, video calls may be disabled in the web interface. Log into the web configuration interface and check the configuration for [Account] →[Codec Settings]→[Enable Video]. If this is set to “Yes”, video is enabled when making calls. If it is set to “No”, video is disabled during calls.
