Configure Quality of Service for an Office VOIP Deployment

There are multiple ways you can use QoS to map ingress phone and PC traffic so that you can give them
each a different quality of service. See
Honor the incoming DSCP value
On both the C-Series or S-Series, if you know traffic originating from the phone is tagged with the DSCP
value of 46 (EF), you might make the associated queue a strict priority queue, as shown in
on the C-Series and S-Series, FTOS maps DSCP 46 to queue 2 (see
chapter.)

Honor the incoming dot1p value
On the C-Series, if you know traffic originating from the phone is tagged with a dot1p value of 5, you
might make the associated queue a strict priority queue, as shown in
maps dot1p priority 5 to queue 2.
