I haven't heard anything about that.

Regardless, the real question is - when are Acme Packet, Ditech, 
Broadsoft, Metaswitch, Lucent, Cisco (and the various other vendors of 
equipment most of the serious providers use at their signaling edge), 
etc. going to support IAX?

The answer is, they're not.

So, if you're buying IAX, by and large you're constraining yourself to 
deal with someone that uses Asterisk inside their platform core.  There 
are some exceptions, in the form of providers that have an Asterisk box 
hanging off their network to do SIP->IAX conversion for the odd one-off 
customers who want it, but it is not the norm.
