Implementing Cisco Collaboration Devices (CICD, legacy) — Question 19

Which protocol allows Cisco Unified Communications Manager to take control of a specific port on a gateway?

Answer options

Correct answer:

Explanation

The correct answer is MGCP, as it is designed for control of media gateways by a call agent, allowing Cisco Unified Communications Manager to manage specific ports. SIP and H.323 are primarily used for establishing sessions and managing calls, while Q.931 is a signaling protocol for ISDN but does not provide control over gateway ports.
