In a more general sense yes, TOS based QoS is better as it relates to
outside your LAN. However, when using m0n0wall (great software!) it's
easiest to assign priority based upon source machine (your * server) IP
or port number.

The examples given previously in this thread are derived from the
built-in traffic shaping wizard. This establishes a series of weighted
ques for data. All you really need to do is be certain that the IAX
traffic is assigned to the highest priority que. Or all traffic to/from
your server can be assigned to the hi priority que.

It all sets up the same thing. Since QoS across the internet is pretty
hard to achieve there's some question as to the actual usefullness of
TOS bits. In future Telco/DSL providers may actually filter traffic
looking for TOS tags to deter your from voip applications.
