That works with the "ip rtp priority" command. Not with an ACL range!
According to docs: "The range operator requires two port numbers. All other
operators require one port number"
So it's not additive there.

scott,
I remeber from my cisco qos training that, second value after port range is
total number of udp ports form the first number.
eg : access-list 110 permit udp any any range 16384 16767 can be read :
16383 + 16767 = 33150
permit udp ports from 16384 to 33150
please clarify
Regards
mohamed
