    Does anyone know the fundamental differences between IAX and SIP?, or indeed
    what IAX and SIP stand for?

    And finally, can I use an iax address with a sipura ATA? and if not, why

    They are different protocols.
    Inter Asterisk eXchange

    Session Initiation Protocol
    No, Hopefully you can work that out for yourself now

    have a look at http://www.voip-info.org/tiki-index.php you will find all the
    info you need there or google for SIP and IAX.

  3. IAX is always on the same port, making firewalling /NATting it a
    doddle. SIP is all over the shop and has STUN as an add-on to try and
    tame it.
