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.
