Auto-answer incoming calls

Allows the system to answer calls automatically.

Mute auto-answered calls

Allows the system to answer calls without turning on the microphone. If you enabled Auto-answer incoming calls, you may want to enable this setting to prevent callers from hearing your private conversations.

Preview my video before placing a call

Lets you verify your local video before you place a call. If you clear this option, the video call is placed immediately when you double-click a Contact's name.

Show recent calls in Contacts list

Adds the calls you've recently placed and received to your Contacts list. These calls appear in a separate Recent Calls group.

Limit Directory search results to people and systems that can support calls

Specifies that Directory search results should show only people who are active Polycom CMA Desktop users or who have systems registered to the CMA system.

Diagnostic Mode

Lets the system use H.261 for video and G.711 for audio. Diagnostic Mode disables many system features such as content sharing, far end camera control, AES encryption, LPR, and advanced audio and video algorithms. Use Basic Mode only when calling systems that fail to operate property with these advanced features.
