This is a very non-traditional deployment. SIPX is hosted and there is an acme sbc sitting in the same network as sipx. all users are remote (behind a firewall) though sipx is setup to use the remote sbc via sipxbridge. The issue they are having is with hairpinned calls via the acme and the itsp. I've suggested to them that they look at using a second itsp for the forwarded calls to test whether the itsp supports it, as some simply do not work. Additionally, I've specified their softphone is incorrectly configured and should be removed from the test environment until it is properly configured/registered.
