[Asterisk-Users] Can you comment on this Qos script? How does one shape RTP?

Just add some iptables rules to prioritize UDP traffic by marking them with 
TOS. (I do this to prioritize game packets at home.)

iptables -t mangle -A PREROUTING -p udp -j TOS --set-tos 0x10
iptables -t mangle -A OUTPUT -p udp -j TOS --set-tos 0x10
iptables -t mangle -A POSTROUTING -p udp -j TOS --set-tos 0x10

Wondershaper puts packets marked TOS 0x10 into the high priority queue.
