Configure IP Networks for Real-Time Voice Traffic 2-6 In addition, you can use VoIP peers to define characteristics such as IP precedence, additional QoS parameters (when RSVP is configured), CODEC, and VAD. Use the ip precedence command to define IP precedence. If you have configured RSVP, use either the req-qos or acc-qos command to configure QoS parameters. Use the codec command to configure specific voice coder rates. Use the vad command to disable voice activation detection and the transmission of silence packets. Refer to the “Configure Dial Peers” section and the “Optimize Dial Peer and Network Interface Configurations” section for additional information about configuring dial peers and dial-peer characteristics. Step 5 You need to configure your Cisco 3600 series router to support voice ports. In general, voice-port commands define the characteristics associated with a particular voice-port signaling type. voice ports on the Cisco 3600 series support three basic voice signaling types: — FXO—Foreign Exchange Office interface — FXS—Foreign Exchange Station interface — E&M—“RecEive and TransMit” interface or the “Ear and Mouth” interface Under most circumstances, the default voice-port command values are adequate to configure FXO and FXS ports to transport voice data over your existing IP network. Because of the inherent complexities involved with PBX networks, E&M ports might need specific voice-port values configured, depending on the specifications of the devices in your telephony network. For information about configuring voice ports, refer to the “Configuring Voice Ports” section. Configure IP Networks for Real-Time Voice Traffic You need to have a well-engineered network end-to-end when running delay-sensitive applications such as VoIP. Fine-tuning your network to adequately support VoIP involves a series of protocols and features geared toward Quality of Service (QoS). It is beyond the scope of this document to explain the specific details relating to wide-scale QoS deployment. Cisco IOS software provides many tools for enabling QoS on your backbone, such as Random Early Detection (RED), Weighted Random Early Detection (WRED), Fancy Queuing (meaning custom, priority, or weighted fair queuing), and IP Precedence. To configure your IP network for real-time voice traffic, you need to take into consideration the entire scope of your network, then select the appropriate QoS tool or tools. The important thing to remember is that QoS must be configured throughout your network—not just on the Cisco 3600 series devices running VoIP—to improve voice network performance. Not all QoS techniques are appropriate for all network routers. Edge routers and backbone routers in your network do not necessarily perform the same operations; the QoS tasks they perform might differ as well. To configure your IP network for real-time voice traffic, you need to take into consideration the functions of both edge and backbone routers in your network, then select the appropriate QoS tool or tools. In general, edge routers perform the following QoS functions: • Packet classification • Admission control • Bandwidth management • Queuing Voice over IP for the Cisco 3600 Series Software Configuration Guide
Configure RSVP for Voice Enable RSVP In general, backbone routers perform the following QoS functions: • High-speed switching and transport • Congestion management • Queue management Scalable QoS solutions require cooperative edge and backbone functions. Configure RSVP for Voice Although not mandatory, some QoS tools have been identified as being valuable in fine-tuning your network to support real-time voice traffic. To configure your IP network for QoS using these tools, perform one or more of the following tasks: • Configure RSVP for Voice • Configure Multilink PPP with Interleaving • Configure RTP Header Compression • Configure Custom Queuing • Configure Weighted Fair Queuing Each of these tasks is discussed in the following sections. RSVP allows end systems to request a particular Quality of Service (QoS) from the network. Real-time voice traffic requires network consistency. Without consistent QoS, real-time traffic can experience jitter, insufficient bandwidth, delay variations, or information loss. RSVP works in conjunction with current queuing mechanisms. It is up to the interface queuing mechanism (such as weighted fair queuing or weighted random early detection) to implement the reservation. RSVP can be equated to a dynamic access list for packet flows. You should configure RSVP to ensure QoS if the following conditions exist in your network: • Small scale voice network implementation • Slow links • Links with high utilization • Links less than 2 Mbps • Need for the best possible voice quality To minimally configure RSVP for voice traffic, you must enable RSVP on each interface where priority needs to be set. By default, RSVP is disabled so that it is backward compatible with systems that do not implement RSVP. To enable RSVP on an interface, use the following command in interface configuration mode: Command Purpose ip rsvp bandwidth [interface-kbps] [single-flow-kbps] Enable RSVP for IP on an interface. This command starts RSVP and sets the bandwidth and single-flow limits. The default maximum bandwidth is up to 75 percent of the bandwidth available on the interface. By default, the amount reservable by a flow can be up to the entire reservable bandwidth. Configuring Voice over IP for the Cisco 3600 Series 2-7
