Configuring Voice-over-IP

If the installer does not start after a few seconds, select Start>Run, and enter d:\setup where d is your CD-ROM drive.

Step 5 Follow the instructions on the screen to install the Cisco ConfigMaker application.

To learn about the Cisco ConfigMaker application, view the online movie, or use Cisco ConfigMaker Help Topics from the help menu.

You need administrative privileges to install the Cisco ConfigMaker application on Windows NT.

Cisco IOS Command-Line Interface

To configure your router from the command-line interface (CLI), refer to this guide, the Cisco 1700 Series Software Configuration Guide, or the Cisco 1751 Router Software Configuration Guide available on the Documentation CD-ROM.

Major Voice over IP Configuration Tasks

Follow these major steps to configure Voice over IP (VoIP) on your router:

Step 1 Configure your IP network to support real-time voice traffic. Before you move to the next step, ping the remote router to make sure you have an IP connection.

Step 2 Configure your router to support voice ports. Follow these steps for your specific requirements:

•Foreign exchange station (FXS) and foreign exchange office (FXO) voice ports

The default voice-port values are usually adequate for both FXS and FXO voice ports. However, if you need to change the default values, refer to the Cisco 1751 Router Software Configuration Guide.

•E&M voice port

The default values for an E&M voice port are not sufficient to enable voice and data transmission over the IP network. E&M values must match those of the connected PBX device. Refer to the “Connecting the FXS, FXO, and E&M VICs to the Network” section on page 4.

•ISDN BRI port

The default values for a basic rate interface (BRI) port are not sufficient to enable voice and data transmission over the IP network. BRI values must match those of the connected PBX device. Refer to the “Connecting the FXS, FXO, and E&M VICs to the Network” section on page 4.

Step 3 Enter configuration mode to configure your router for VoIP traffic. Refer to the “Configuring Voice-over-IP” section on page 10.

Step 4 Save the configuration. Refer to the “Saving the Configuration” section on page 13.

Step 5 Establish a dial plan to determine how the call can be routed. Use the dial-peer voice command to define dial peers and to implement the dial plan. Refer to the “Dial Plan” section on page 14.

Step 6 Fine-tune your network to adequately support VoIP by configuring a series of protocols and features for quality of service (QoS). Refer to the “Tuning Parameters for Real-Time Voice Traffic” section on page 25.
