This series of interactive documents uses a typical head office and branch
office in order to demonstrate some common voice network configurations. This

You can use one of these methods in order to configure an MGCP gateway in Cisco IOS for the RTP location:
- Automatic configuration (in which the MGCP gateway downloads its configuration from CallManager)
- Manual configuration
Once you configure the MGCP Unified CallManager Gateway (RTP) Interactive Voice Network Configuration Example, this configuration is created automatically with these commands:
ccm-manager config server 22.214.171.124
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.
