3.match cos 5, ip prec 5, dscp (routing protocols may use the same cos,
prec, dscp value too, not sure this is the right way to classify voice)

Few comments:
-Cos 5 may be present only in 802.1q|ISL tagged frames
-Routing protocol traffic uses ipprec 6 (internetwork control)

Slight correction though: only OSPF Hello packets are marked with IP Prec 6.
