asterisk users - Jan 2005 - IAX on multiple ports

Is it possible to listen on more than one port within a single instance 
of *?  I have an engineer in Iraq that we need voice comms with, but the 
gov't limits traffic to ports 80,443, 25, and 110.  Can I set up IAX to 
listen on port 80 AND the regular IAX port?

Or will I have to set up some weird TCP tunnel?
