A new release of m0n0wall with a completely revamped traffic shaper
that makes most of the power of dummynet available through the webGUI
will be released later this week. The shaper has been split up to
provide separate lists for rules, pipes and queues, where each rule can
be associated with either a pipe or a queue.
I guess you could solve this problem for the upstream by making two
queues linked to the same pipe (and set the pipe's bandwidth to
something slightly below the effective upstream throughput to bring the
queue into m0n0wall instead of the router), but with different weights,
and then have traffic from that IP phone go to the queue with the
higher weight, while everything else goes to the other queue. That
doesn't work very well with downstream traffic, though, as you have no
control over the order in which packets come in from your ISP.
