[cisco-voip] QoS ?

[Jonathan Charles]

You should absolutely be doing a match-any.

The problem runs in when you have traffic marked CoS 3 and not DSCP 31

To be honest though, AF31 will have Precedence 3 as a part of it (you need
to break down the binary to see it).

The point here is that you want to prioritize your signalling traffic, which
can be CoS 3, Precedence 3 or DSCP AF31... since we want to match any of
them, we need to do a match-any.
