Indeed.  In addition to having no support among manufacturers of VoIP 
network elements used in service delivery platforms of nontrivial size 
(I am not referring to phones or ATAs), IAX has a fundamental design 
flaw that makes it unworkable for large amounts of traffic.

Its principal issue is that precisely because of that aspect of which is 
touted most - that it mixes the signaling and bearer plane into one 
packet stream - it cannot be used in larger, more decoupled assemblies 
of numerous media gateways controlled by one peripheral signaling agent.

No, I don't have any direct quotations from Level3, Global Crossing, XO, 
or a handful of smaller vendors that the rest of these ITSPs are 
reselling in some shape or form saying that they don't do IAX handoff. 
However, my main line of work is in service delivery platform 
engineering and scalable architecture, and I work with actual carriers a 
fair bit.

Like you, I can make some conclusions from my experience and knowledge 
that has crystallised, and refer to it on the basis of inductive claims.

To the best of my knowledge, it is a fact that nobody outside the 
Asterisk cottage industry gives a hoot about IAX.
