I just spent some time doing this myself. If your routers already can
prioritize traffic based on the TOS bits in your IP traffic, setting the
tos in iax.conf should be the first place to start. If your routers
don't do that already you will need to mess with setting up
queuing/policies on the routers. Here are some places to start:
Here are some awesome descriptions on how QoS works and what the
different methods of implementing queuing and traffic shaping on Cisco
hardware are. They may be a bit dated depending on what kind or routers
you are using:

http://www.netcraftsmen.net/welcher/papers/qos2.html
http://www.netcraftsmen.net/welcher/papers/qos3.html
Here are some pages from the wiki that talk about QoS on cisco hardware.
Not sure what "type" of queueing this uses, but it allocates a certain
amount of available traffic to voice traffic. Any unused voice traffic
will be shared by what's left:

This page seems to talk about CAR (Committed Access Rate):
http://www.voip-info.org/wiki/view/QoS+Cisco+IOS
I ended up using priority queuing on my routers, giving voice first
priority and everything else lower priorities. Not the best solution but
it was the easiest for me to implement with the versions of IOS I have.
If you would like to see my configs, let me know.
