Nicolas, When working with ranges in a class map definition we define the starting port number and the range of ports, ie 16384 as staring port and 16383 more ports, that is up to port 32767.
When using ACL we define a range: ie starting and ending port. Moreover when we work with ACL we define ANY traffic using UDP and with class-maps only the RTP using UDP ports. To talk about something deeper however is that a good thing of ACL though is that we have included RTCP (odd even port numbers) as well, not in the class map matching RTP Only. //r.a.
