I've got another question about Cisco 9951 IP phones. If Cisco Unified Video Camera is connected and enabled, and video capabilities are enabled, by default all calls become video calls if both endpoints support it. This is not convenient. I would like to have a dedicated 'VideoCall' button (preferably softkey) to establish video calls and leave all calls audio-only by default. How can this be done?
The problem with this approach is that the established call is still a video call with the corresponding menu and black screen. When a video call is established, the menu items change and you cannot see active sessions because of the video (even if it's not fullscreen). There is actually an "Auto Transmit Video" setting under "Accessories > Cisco Unified Video Camera" which controls whether video stream is sent by default on all video calls, but this is not what I want because of the above mentioned menu and screen changes during a video call.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
1) Login into the CLI of the Publisher.
