Configuring Cisco Unified Communications Manager for MGCP Gateway Control

C.

If an engineer wants to have Cisco Unified Communications Manager control the configuration for an MGCP gateway, they need to perform the following action:

A. Apply the ccm-manager configuration commands to the gateway.

Explanation: The ccm-manager configuration commands are used to enable the Cisco CallManager to manage and configure an MGCP gateway. These commands are used to establish a communication channel between the gateway and the CallManager, which allows the CallManager to control the gateway's configuration. The ccm-manager configuration commands should be applied to the gateway's configuration using the gateway's command line interface (CLI). Here are the steps to apply the ccm-manager configuration commands:

1. Access the gateway's CLI by connecting to the gateway using a terminal emulator program.
2. Enter configuration mode by typing the command "configure terminal" at the prompt.
3. Enter the ccm-manager configuration mode by typing the command "ccm-manager config" at the prompt.
4. Specify the IP address of the CallManager by typing the command "ccm-manager mgcp" followed by the IP address of the CallManager.
5. Save the configuration changes by typing the command "write memory" at the prompt.

After completing these steps, the gateway will be configured to allow the CallManager to manage and configure the gateway's settings.

Option B is incorrect because uploading a custom configuration in the TFTP server in Cisco Unified CM does not allow the CallManager to control the gateway's configuration.

Option C is incorrect because checking the auto-configuration check box does not enable the CallManager to manage and configure the gateway's settings.

Option D is incorrect because configuring the Cisco Unified CM's IP in voice service VoIP is not a valid configuration step for enabling the CallManager to control the gateway's configuration.
