    There are several possible things: basically NAT and codecs.

    Have you tried the phone with some other service provider (eg
    voipuser.org or fwd)? You can sign up with them for free and do some
    things, and their SIP systems seem to be much more stable/sensible than
    Voipbuster's. [alas, they don't have the same free calls] If those
    are working, you probably have the firewall etc set up OK. If you can't
    get those to work, you need to look into NAT/firewall issues. (I have
    found so far that with NAPT you don't need STUN and all those

    The most likely problem from my recent experience is the codec choice.
    Voipbuster seems to negotiate use of codecs it then can't honour; and
    then give a '403 forbidden' return code. I have restricted my codecs to
    G711a and G711u on a Grandmaster 486 and that worked for me. I haven't
    tried sjphone with Voipbuster (I had instability problems with it even
    before I added the Voipbuster dimension)

    Look for lots of information on forums at voipuser.org and

    Good luck
