The difference between the 1st and 2nd statement is as follows:
The first statement (the udp 16384...) matched the payload and
signal/control traffic where the "IP RTP" statement captures the data
packets only. The first statement ensures that ALL RTP traffic (payload and
signal) packets get matched. If I remember correctly, each RTP stream uses
4 consecutive ports, starting with the first even port above 16384, so the
first stream uses 16384-16387. It's been a while, but I think that's
correct.

i have no idea if it is working........it's a lab scenario
i wasn't sure if the 'match rtp' somehow included the tcp 1720. i really
don't understand the difference between the two statements or why or why not
they would be used. any insite you could give would be most helpful!
