Customer is using Cisco IP phones (79XX) and CUVA for video.
When they don't want to use video for a specific call, they just turn off video at the beginning of the call, but in this case they still get a black screen.
Is there any way to prevent this black screen from appearing when the call is just an audio call?
If the only way is disabling video capabilities in the device, is there any way in which the end user can do it without contacting administrator?
Thanks in advance.
Best regards,
Carmen
