I have reset my ser.cfg as before (no auth in INVITE) and it still
allow unREGISTERed lines to call. But there are differences between a
unREGISTERed line making a call and a REGISTERed line making the same
call (user 6767 does not exist in SER):

unREGISTERed making a call (my.snom.com was my phone IP and
ser.ourdomain.com was our ser's IP):

Yes, only one packet. My Snom shows me the call is on its way and I
hear the other side ringing.

Now, for the same result, here's what I have for the REGISTERed line:

I guess there should be something in ser.cfg to disallow the call in
the first case, but what?
