DSCP Service Parameters for Cisco Telepresence Audio
Which DSCP service parameter is configured for Cisco TS endpoints and Cisco Communication Manager endpoints?
Community Votes
100% of anonymous learners picked answer C. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The exam tests attention to detail regarding specific configuration field names; the trap is confusing standard video call audio with specialized Telepresence audio parameters.
This question tests knowledge of specific DSCP service parameter naming conventions in CUCM. The correct setting is explicitly named 'DSCP for audio portion of Cisco Telepresence calls' to distinguish it from standard video call audio.
Candidates often select 'DSCP for audio portion of video calls' because they assume all video calls use the same audio DSCP marking, missing the specific distinction for Cisco Telepresence endpoints.

Why the Answer Is Correct
The correct answer is C because Cisco Unified Communications Manager (CUCM) maintains distinct service parameters for different media types. Specifically, there is a unique parameter labeled "DSCP for audio portion of Cisco Telepresence calls" designed to handle the differentiated services code point requirements for high-definition Telepresence audio streams separately from standard video.Why the Other Options Are Wrong
Option A refers to standard video calls, which use a different service parameter than Telepresence-specific setups. Option B applies only to pure audio calls (voice), not mixed media. Option D refers to the video payload itself, not the audio component. Confusing these categories leads to incorrect QoS application.Community Comment Notes
Community discussion highlights ambiguity in older exam dumps versus current documentation. While some users argue for Option B due to slight wording variations in titles, official Cisco documentation confirms the existence of the specific Telepresence audio parameter. It is crucial to recognize that Telepresence has its own dedicated DSCP settings separate from general video or voice.Official Reference
Exam Strategy
When studying CUCM service parameters, memorize the exact naming conventions rather than just the concepts. Pay special attention to parameters that differentiate between 'Video Calls', 'Telepresence Calls', and their respective audio portions, as exams often test this granularity.
