The table indicates the most common DSCP values and their occurrence in all the RTP packets :

 ●  DSCP = 0 Default Forwarding which means no QoS implemented - this is also called Best effort
 ●  DSCP = AF31 Assured Forwarding Class 3 Low drop probability
 ●  DSCP = AF32 Assured Forwarding Class 3 Medium drop probability
 ●  DSCP = AF33 Assured Forwarding Class 3 High drop probability
