Which DSCP service parameter is configured for Cisco TS endpoints and Cisco Communication Manager endpoints?

"DSCP for audio portion of video calls" is a more specific parameter for the audio component embedded within a video stream, not for general standalone audio calls from these endpoints.

The "DSCP for audio calls" service parameter in Cisco UCM is specifically used to define the Differentiated Services Code Point value that will be marked on IP packets containing audio traffic originating from both Cisco TS endpoints and standard UCM IP phone endpoints. This ensures proper Quality of Service (QoS) classification for voice.

"DSCP for audio portion of Cisco Telepresence calls" is a more specific variant of option A, and "DSCP for audio calls" is the broader, more encompassing parameter for all audio calls from these endpoints.

"DSCP for video calls" specifically refers to the video component of a call, not the audio, and these endpoints also handle pure audio calls.
