ok, sounds interesting...i'll have to explore this one.
if one was to remember all of the ports and what-not....what would i be
missing here
access-list 101 permit tcp any any eq 1720
access-list 101 permit udp any any range 16384 32767
?

Take off any map-class configurations, add a bandwidth statement in to
an interface then run auto qos voip, it is a macro that ads all the
class maps and so forth in to your configuration. If you want to
simplify your life regarding identifying all the port number for voice
signaling, it is worth getting familiar with the operation of this
command.

A good trick for the lab is to get used to using auto qos, it creates
all the class maps to identify all voice traffic, so get used to running
auto qos, noting what class maps are created, then running no auto qos
to take it out of the configuration and you can use the parts you want.

Subject: classification of voice traffic
there seems to be many different ways to classify and filter voice
traffic that i've seen, via rtp, rsvp, and h.323 signaling...
is there any one filter method that will filter all type of voice
traffic?
if you filter the following:
class-map match-all voice
match access-group 101
access-list 101 permit tcp any any eq 1720 access-list 101 permit udp
any any range 16384 32767
are you essentially matching all voice traffic?
how does that differ from:
class-map match-all voice
match pro rtp
i believe that rtp range is the same for udp ports, so is the only
difference in the two examples the signaling with the tcp statement?
