Hello there, I'm having a weird issue with a Cisco 8865 phone running MPP and registered on webex. When the user places an outgoing call to an external cell phone, the camera on his 8865 will turn on and show a self view. We don't want to disable the camera entirely since he uses the video function when in a video call, but when its a regular voice call, he does not want his camera on. Is there a specific setting that he may accidentally have on or something?
