Configuring Quality of Service <strong>for</strong> an Office VOIP Deployment<br />

There are multiple ways you can use QoS to map ingress phone and PC traffic so that you can give <strong>the</strong>m<br />

each a different quality of service. See Chapter 27, Quality of Service.<br />

Honoring <strong>the</strong> incoming DSCP value<br />

On both <strong>the</strong> C-<strong>Series</strong> or S-<strong>Series</strong>, if you know traffic originating from <strong>the</strong> phone is tagged with <strong>the</strong> DSCP<br />

value of 46 (EF), you might make <strong>the</strong> associated queue a strict priority queue, as shown in Figure 459; on<br />

<strong>the</strong> C-<strong>Series</strong> and S-<strong>Series</strong>, <strong>FTOS</strong> maps DSCP 46 to queue 3 (see Table 55 on page 572 in <strong>the</strong> QoS chapter.)<br />
