•
IP address of the TFTP server in the network and routing information required for access
•
Sufficient information for configuration of an IP interface on the device
With this configuration information available at startup, the MGCP gateway downloads the XML file
from the TFTP server. The gateway parses the XML file, converts the information to appropriate
Cisco IOS configuration commands, and configures itself to run in the VoIP network. Finally, the
gateway registers itself with Cisco Unified Communications Manager using an RSIP message. At that
point, the MGCP gateway is ready for service in the network.
After a successful configuration download, the MGCP gateway saves the running configuration to
nonvolatile random-access memory (NVRAM), which updates the startup configuration. Any
manually-added configuration parameters are also saved to NVRAM if they were not previously saved.
Manually-added configuration parameters are updates to the configuration that were made using the
command-line interface (CLI). Manual configuration updates are separate from the automatic
configuration updates made during the configuration download process.
In the event of a configuration failure, the MGCP gateway attempts to restore its current configuration
by copying the startup configuration from NVRAM into the running configuration. Because this
overwrites the running configuration, any manually added configuration parameters could be lost if they
were not saved to NVRAM before running the automatic configuration-download process.

Prerequisites for Single-Point Configuration for MGCP Gateways
•
MGCP should be configured in your VoIP network through the Cisco Communications Manager
web-based graphical user interface (GUI).
•
The IP hostname should match the gateway name that is specified in the Cisco Unified
Communications Manager configuration.
