The reasoning for the match is the starting port # (16384) and the # of
ports to include (16383), and 16384 + 16383 = 32767, which is the high
end of the range.
16383 ports starting with # 16384 are for H.323 voice
16383 ports starting with # 32768 are for H.323 whiteboard
16383 ports starting with # 49152 are for H.323 video
Just in case you have to match other things. :)
As for matching on ip prec 5 or DSCP EF, you SHOULD be cool with that,
but it will depend on your application (just to be safe).

Subject: Re: ip rtp priority on frame relay
For voice traffic the range is 16384 to 32767, (just remember 16384 x 2
-1), you can also match on precedence 5, or dscp ef if using CBWFQ.. but
for rtp priority, (for reasons I am still unclear on..), all the docs I
have read say to match on 16384 and 16383... For RTP use:
map-class frame MYMAP
Frame ip rtp priority 16384 16383 45
Bandwidth 32
RTP example:
Map-class frame MYMAP
Frame bc 640
Frame cir 64000
Frame be 0
No frame adaptive
Frame fair-queue
Frame fragment 80
Frame ip rtp priority 16384 16383 45
