Which?

IAX is *not* a signalling protocol. It is a VoIP protocol.

And that's the whole point. H.323, SIP, et al those are all signalling
protocols, half protocols so to speak. IAX is a self-contained, true
internet protocol. In a world where everything is moving towards peer to
peer that is an advantage. Dedicated protocols for signalling-only have
been designed for large telcos and yesterday's telco infrastructure, not
for the future of voice on the net peer to peer style.

Do you actually know how IAX works? There is no such thing as IAX/RTP,
none whatsoever. Again, that's the whole point of IAX.

If you refer to the urban legend that IAX always needs a server to stay
in the media path, then you would be wrong. IAX has a mechanism that for
all practical purposes is equivalent to a SIP reinvite through which the
end points then transition to a mode by which they communicate directly
peer to peer.

There is already one chipmaker who thought that IAX was important or
competitive advantage enough to embed it into their chip. So, precedence
has been set already. This trend can be expected to continue. And, no,
Digium had no involvement in this (Mark please correct me if I am
wrong).
