Configure

You can use one of these methods in order to configure an MGCP gateway in Cisco IOS Software for the San Jose location:

• Automatic configuration (in which the MGCP gateway downloads its configuration from Unified CallManager)
• Manual configuration

Automatic Configuration

This configuration is created automatically with these commands once you configure the San Jose gateway (as described in MGCP Unified CallManager Gateway (San Jose) Interactive Voice Network Configuration Example).

ccm-manager mgcp
ccm-manager music-on-hold
ccm-manager config server 171.69.103.225
ccm-manager config

Manual Configuration

For the manual configuration, the commands in this section are typed manually depending on desired configuration (with the exception of the ccm-manager config command).

Note: Only the relevant MGCP configuration is shown here.
