 cant restrict the invite by the sipphone no need regiestion.

    Are you authenticating INVITEs differently than you are authenticating
 registrations?  In other words, are the authentication realm and required
 credentials different for your proxy_challenge() than they are for
 your www_challenge() for handling REGISTER requests?

    If they are, it seems that all you should have to do is do a lookup() 
 and see if it fails.  Presumably, you are doing a save() into your 
 registrar/usrloc only on valid REGISTER challenges?

    i.e.

      if(is_method("INVITE")) {
              if(!lookup("location")) {

           if(!registered("location")) {
is sufficient

btw: this does not give you any security
