I agree bandwidth is the limit, however the reason to use IAX is it is saving bandwidth. I am runging 2 Trixbox CE with IAX over a 2 Mbit line. I have never had any isues with the IAX trunk. I wish that I could get son good IAX phones to the office, tan would we skip on Trixbox and run the phones directly over a VPN Chanel. SIP over VPN are giving more hassle then IAX sound wise.
