far asterisk seems to use 1:10 while all other traffic uses 1:102. How
does one packet shape RTP?
Thanks for any help.

I'm using the same script, but I found it searching Google. Yours seems to be incomplete. My script follows:
#!/bin/sh
TCOP="add" IPTOP="-A"
if [ "$1" == "stop" ]; then
echo "Stopping..."
TCOP="del"
IPTOP="-D"

# 1:10 is the class for VOIP traffic, pfifo qdisc # 1:20 is for bulk traffic (htb, leaves use sfq) # 1:30 is the class that interactive and TCP SYN/ACK traffic (sfq qdisc)
# 1:20 is further split up into different kinds of bulk traffic: web, mail and
# everything else. 1:100-102 fight amongst themselves for their slice of excess
# bandwidth, and in turn 1:10,20 and 30 then fight for any excess above their
# minimum rates.
# which interface to throw all this on (DSL) IF=eth2

# rate is 65% of max rate
# we don't let it go to 100% because we don't want the DSL modem (Pairgain MegaBit Modem 300S)
# to have a ton of packets in their buffers. *we* want to do the buffering.
