Chapter 5 Configuring the Voice Interfaces

Configuring Voice Interfaces

• Establish a working telephony network based on the dial plan for your company.

• Integrate your dial plan and telephony network into your existing IP network topology.

Before you configure an interface, have the following information available:

• Protocols you plan to route on the new interface

• IP addresses, subnet masks, network numbers, zones, or other information related to the routing

protocol

Obtain this information from your system administrator or network plan before you begin AGM

configuration.

Whenever you install a new interface, or if you want to change the configuration of an existing interface,

you must configure the interface. If you replace a module that was already configured, the AGM

recognizes it and brings up the interface in the existing configuration.

Configuring Voice Interfaces

Use a voice interface card (VIC) for a voice connection. For information about installing these

components in a AGM, see Installing Voice and WAN Interface Modules, page 2-6.

Timesaver Before you begin, disconnect all WAN cables from the AGM to prevent it from trying to run the

AutoInstall process. The AGM tries to run AutoInstall when you power it on if there is a WAN

connection on both ends and the AGM does not have a valid configuration file stored in NVRAM

(for instance, when you add a new interface). The AGM can take several minutes to determine that

AutoInstall is not connected to a remote TCP/IP host.

To configure a voice interface, use configuration mode (manual configuration). In this mode, you can

enter Cisco IOS commands at the AGM prompt.

To enter configuration mode, follow this procedure:

Step 1 Connect a console to the Catalyst 4000 family switch supervisor engine.

Step 2 Power on the AGM by inserting it into a powered chassis or by powering on the chassis. If the current

configuration is no longer valid, after about one minute you see the following prompt:

Would you like to enter the initial dialog? [yes/no]:

Enter No. You will enter the normal operating mode of the AGM. If the current configuration is valid,

you enter the normal operating mode automatically.

Step 3 After a few seconds, you see the user EXEC prompt (gateway>). Enter enable and the password to enter

enable mode:

gateway> enable

Password: <

password>

Configuration changes can be made only in enable mode. The prompt changes to the privileged EXEC

(enable) prompt:

gateway#

Step 4 Enter the configure terminal command to enter configuration mode:

gateway# configure terminal
