Mike,
In my QoS policy I specify different levels of QoS
In the lab the may ask you to configure dif levels according to traffiic
type.
The RTP ports are 16384 to 32768, but in addtion they could ask you to
configure WFQ or LLC.
It will depend on the requirement if any addtional step is required for
voice traffic EF or signaling traffic AF31.
