Feature Overview
MGCP voice gateway interoperability with Cisco CallManager allows modular access routers to act as
redundant failover MGCP gateways. You can enable IP telephony and Cisco CallManager solutions
using Cisco 2600 and Cisco 3600 series routers as voice gateways. This allows you to use the Cisco 2600
and 3600 platforms already in your networks as MGCP gateways within an IP telephony architecture.

An MGCP gateway handles the translation between audio signals and the packet network. The gateways
interact with a call agent (also called a Media Gateway Controller or MGC) that performs signal and call
processing on gateway calls.

In the MGCP configurations that Cisco IOS supports, the gateway can be any of the following:
•
Cisco router
•
Access server
•
Cable modem
The call agent is either of the following:
•
A server from a third-party vendor
•
Cisco CallManager
With MGCP, gateways are defined as secondary devices under control of the call agent. MGCP uses
endpoints and connections to construct a call. Endpoints are sources of or destinations for data, and can
be physical or logical locations in a device. Connections can be point-to-point or multipoint. The call
agent manages connections between endpoints and controls how gateways function. (See

MGCP
An MGCP gateway derives most of the configuration it requires from the call agent. To configure an
MGCP gateway, you simply identify the call agent associated with the gateway and identify the gateway
to the call agent.
