It was originally for use with some of our internal UAs which don't handle authentication properly.... and I was simply too lazy to set up the authentication with trust tables.
I know. Slackness coming back to bite me in the ass. But it's fixed now.

I do not understand why you do not authenticate the users.
Using existinguser@ourdomain.com is at least as bad as nonexistinguser@ourdomain.com.
You also have to check that some persons do not misuse existing accounts.
I would never allow any local user to use my SIP proxy without authentication. (Of course incoming calls are allowed without authentication).
Allowing outgoing calls without authentication (authentication implies that only local users are allowed to use the proxy) is a bad thing (the same like open mail relays.)

Well... my hack seems to work. I'll see if I managed to break anything, though. It shouldn't affect reinvites or require using trusted tables as other machines aren't going to claim they're local users.
The Snom phones will use PKI certs if you want. But I can't guarantee all our users will want to buy one. ;)
I'm less interested in checking if the host is local to the proxy, though as, again, we're an open proxy. I just want to avoid bob@ourdomain.com (a non-existent user) using the ourdomain.com proxy to send calls through, having it trace back to us and causing problems.

there is even a function to check if from host is local to your proxy.
I'll give it a shot. Seems kind of backward, though.
another option is to use pki certificates that both UAs can verify, but i haven't seen those implemented in UAs.
