Can someone tell me the difference between these two commands. We have routers with QoS configurations done both ways. I know that the "match ip rtp 16384 16383" matches all even RTP ports, which are used for payload and does not match RTP odd ports, which are used signaling. But what is the result if you use "match ip rtp 16383 16383"? This command is also found in some old Cisco documentation but I can't find what exactly it's matching.
