match discord voip traffic

[sash1010]

i try to match discord voip with class-map rule

match protocol rtp

no success 

i seen voip traffic is udp with destination port range about 50000-50100

why match protocol rtp is not working?

maybe is better to use access-list?

what is the right way?

Post full configuration, see any other ACL have overlap :

TCP/UDP

46

Expedited Forwarding (EF)

example :

Policy Map My_Policy

    Class My-Audio

     trust dscp

      set dscp ef

    Class My-Video

      trust dscp

      set dscp af41

     Class class-default

it's not about mark with dscp, i try to classify voice traffic to separate class. ( class-map VOICE in my case. )
