This is what I found from an older draft:
http://www.cs.columbia.edu/~hgs/rtp/drafts/draft-aboba-rtp-http-02.txt
4.5. Port numbers
Although there is no official policy on this, current practice dic-
tates usage of port ranges as follows:
[0, 16384] - lowest priority, unclassified
[16384, 32768] - highest priority, i.e. audio
[32768, 49152] - medium priority, i.e. whiteboard
[49152, 65536] - low priority, i.e. video
It is recommended that unreliable multicast HTTP use the medium prior-
ity port range.

Hi Lee,
I've always thought the entire range was from 16384 to 32767, which would
make your example be:
frame-relay ip rtp priority 16384 16383 512
Please refer to the little matrix titled parameter:
http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a00801048
19.shtml#frame_relay_ip
"Moreover, you can specify the entire voice port range (16384 to 32767) to
ensure that all voice traffic is given strict priority service"
HTH,
Sean
