<div>As they all said above.</div>

<div>I think IAX is supported on some Cisco equipment for WAN connectivity, making it useful for interconnecting back-end systems and servers (e.g. server to server rather than server to UA).</div>
<div> </div>
<div>I believe IAX uses the same port(s) for signalling as for media, as compared to SIP vs RTP using separate streams. This makes it easier when doing port-forwarding and may give it an advantage for NAT traversal.</div>
<div> </div>
<div>That being said, it is not yet an officially recognised protocol (from what I heard) and has not yet been as widely adopted as SIP. In short, you will find more SIP-enabled devices than you will find IAX devices, though there are some IAX softphones around.
