Implementing Cisco Advanced Call Control and Mobility Services (CLACCM) — Question 115

Users report silence on the line when they try to connect to external voice numbers. The company is using Cisco 8865 phones with Cisco UCM connected to a gateway with two T1 circuits. The MGCP server seems to be responding. Which action must the engineer take to begin to investigate the media for this type of issue?

Answer options

• A. Run RTMP on the Cisco router.
• B. Verify that the MGCP service is running under serviceability in Cisco UCM.
• C. Run the debug mgcp media command on the Cisco router.
• D. Run the debug H.323 gateway command on the Cisco router.

Correct answer: C

Explanation

The correct answer is C because running the debug mgcp media command on the Cisco router allows the engineer to capture and analyze media traffic, which is critical for diagnosing audio issues. Option A is incorrect as RTMP is not relevant for this type of media issue. Option B, while important, does not directly investigate the media itself, and option D pertains to H.323, which is not applicable in this MGCP scenario.
