Chapter 4 Configuring Voice
Configuring the Voice Interface
Note The Cisco VG202, Cisco VG202XM, Cisco VG204, and Cisco VG204XM voice gateways are fixed
voice gateways and do not support interface cards.
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
Timesaver Obtain this information from your system administrator or network plan before you begin configuring
your voice gateway.
To configure a voice interface, you must use configuration mode (manual configuration). In this mode,
you can enter Cisco IOS commands through the CLI.
Procedure
Step 1 Connect a console to the voice gateway as described in the Cisco VG202, Cisco VG202XM,
Cisco VG204, and Cisco VG204XM Voice Gateways Hardware Installation Guide.
Step 2 Power on the voice gateway. If the current configuration is no longer valid, after about one minute you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]:
Answer no. You now enter the normal operating mode of the voice gateway.
Note 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 (VG>). Type enable and the password to enter enable
mode:
VG> enable
Password: <password>
The prompt changes to the privileged EXEC (enable) prompt (VG#):
VG#
Step 4 Enter the configure terminal command to enter configuration mode:
VG# configure terminal
VG(config)#
The voice gateway enters global configuration mode, indicated by the VG(config)# prompt.
Step 5 If you have not configured the voice gateway before, or you want to change the configuration, use Cisco
IOS commands to configure global parameters, passwords, network management, and routing protocols.
In this example, IP routing is enabled:
VG(config)# ip routing
For complete information about global configuration commands, see the Cisco IOS configuration guides
and command references.
