Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 46

An engineer must configure an MGCP gateway and register it to Cisco Unified Communications Manager. Which prerequisite must be met before applying the gateway commands to enable MGCP?

Answer options

• A. The MGCP gateway and the Cisco Unified CM must be able to communicate aver ports 5060 and 5061.
• B. Cisco Unified CM and the MGCP gateway must utilize the SIP OPTIONS ping feature to monitor status.
• C. The MGCP gateway must have voice service VoIP configured.
• D. The MGCP gateway and the Cisco Unified CM must be able to communicate over ports 2427, 2428, and 2727.

Correct answer: D

Explanation

The correct answer is D because the MGCP protocol requires communication over specific ports, including 2427, 2428, and 2727, to function properly with Cisco Unified CM. Options A and B mention different ports and features that are not essential for MGCP registration, while option C, although relevant to voice service, does not address the registration communication requirements.
