Configuring Voice-over-IP

Entering Configuration Mode

You can configure your router for VoIP by entering commands at the CLI. This method of entering

commands is called configuration mode.

Note VoIP requires one of the following IOS Release 11.3(1)T (or later) feature sets: IP Plus, Desktop Plus,

or Enterprise Plus.

Follow these steps to enter configuration mode:

Step 1 Connect a terminal or PC to the router.

To configure the router with a PC, the PC must have some type of terminal emulation software installed.

The software should be configured with the following parameters: 9600 baud, 8 data bits, no parity, 1

stop bit.

Step 2 Power up the router.

Step 3 If the current configuration is no longer valid (for instance, because you added an interface), after about

1 minute you will see the following prompt:

Would you like to enter the initial configuration dialog? [yes]:

Do not use the yes default. You need to enter no to enter the normal operating mode of the router.

Note If the current configuration is valid, you enter the normal operating mode automatically.

Step 4 At the user EXEC prompt (Router>), enter enable and the password to enter enable mode:

Router> enable

Password:

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

(enable) prompt (Router#):

Router#

Step 5 Enter the following command to enter global configuration mode:

Router# config terminal

Router(config)#

Step 6 If you have not configured the router before or want to change the configuration, you need to configure

global parameters, passwords, network management, and routing protocols. In this example, IP routing,

AppleTalk routing, and IPX routing are all enabled:

Router(config)# ip routing

Router(config)# appletalk routing

Router(config)# ipx routing

For complete information about the global configuration commands and about configuring LAN and

WAN interfaces on your router, refer to the Cisco IOS configuration guides and command references.

The rest of this guide explains how to configure your router for VoIP traffic.
