I use IAX with unlimitel.ca on Asterisk 1.6, and I haven't had any 
issues at all.

The choice of router/NAT is critical though. Unlimitel recommended the 
SnapGear 560 to me, and it eliminated all the issues I was having with 
IAX going through my Sonicwall devices.

Just another datapoint for you...
