The correct answer is D - The MGCP gateway and the Cisco Unified CM must be able to communicate over ports 2427, 2428, and 2727.
Media Gateway Control Protocol (MGCP) is a protocol used to control media gateways in a Voice over IP (VoIP) network. When an MGCP gateway is used in conjunction with Cisco Unified Communications Manager (CUCM), the gateway must be registered with CUCM so that it can be managed and controlled by CUCM.
Before configuring an MGCP gateway and registering it with CUCM, the following prerequisites must be met:
The gateway must be configured with IP connectivity to the CUCM cluster. This means that the gateway must be able to reach the CUCM servers over the network.
The gateway must be configured with the correct time zone and NTP settings.
The gateway must have a unique hostname and IP address.
The gateway must have the correct firmware and software installed.
The MGCP protocol must be enabled on the gateway.
Once these prerequisites have been met, the engineer can configure the MGCP gateway and register it with CUCM. The commands used to enable MGCP on the gateway will vary depending on the gateway model and software version, but typically involve configuring the gateway to communicate with CUCM over specific ports. In the case of this question, the correct answer is D - the MGCP gateway and the CUCM must be able to communicate over ports 2427, 2428, and 2727. These ports are used by MGCP to transmit and receive control messages between the gateway and CUCM.
In summary, before configuring an MGCP gateway and registering it with CUCM, the gateway must meet certain prerequisites, including having IP connectivity to the CUCM cluster, the correct time zone and NTP settings, a unique hostname and IP address, and the correct firmware and software. Once these prerequisites are met, the engineer can configure the MGCP gateway and register it with CUCM, typically by enabling MGCP and configuring the gateway to communicate with CUCM over specific ports. In the case of this question, the correct answer is D - the MGCP gateway and the CUCM must be able to communicate over ports 2427, 2428, and 2727.
