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?
