To configure VoIP on your router, you need to perform the following steps:

Step 1 . Configure your IP network to support real-time voice traffic. Refer to the following section for information about selecting and configuring the appropriate QoS tool or tools to optimize voice traffic on your network.

Step 2 . (Optional) If you plan to run VoIP over Frame Relay, you need to consider certain factors so that VoIP runs smoothly. For example, a public Frame Relay cloud provides no guarantees for QoS. Refer to the "Configure Frame Relay for VoIP" section for information about deploying VoIP over Frame Relay.

Step 3 . Use the num-exp command to configure number expansion if your telephone network is configured so that you can reach a destination by dialing only a portion (an extension number) of the full E.164 telephone number. Refer to the "Configure Number Expansion" section for information about number expansion.

Step 4 . Use the dial-peer voice command to define dial peers and switch to the dial-peer configuration mode. Refer to the "Configure Dial Peers" section and the "Additional VoIP Dial Peer Configurations" section for additional information about configuring dial peers and dial-peer characteristics.

Step 5 . Configure your router to support voice ports. Refer to the "Configure Voice Ports" section for information about configuring voice ports.
