I've got a new openser config I'm testing with a secondary server (1.1.1
on Centos5), but I'm having a few problems getting some clients, X-lite
3.0 and an ATA from draytek, who are unable to register with the server.
Watching with ngrep on the server and wireshark locally I see the server
and the client communicating, the client sends a register to the server,
the server says 401 Unauthorized and generates a realm and nonce, but
instead of going on with the next step in the register process (adding
one to the Cseq and generating a nonce of its own) the client just
doesn't seem to notice that the 401 was sent (could they possibly be
expecting a 407?) they just keep trying with the first step in the process.
Is this an error in my config (sending a 401 instead of something else)
or a deficiency in the client ( I have a few grandstream phones which
work perfectly)...
Here's a few lines from the ngrep output...

The ATA is .30 and has a public IP, as does the Server (.17)
I personally can't see any errors in terms of where the replies are
being sent, but I may be overlooking something quite obvious.
The useful parts of my openser.cfg (I have use domain as 1 in auth,
auth_db, etc, but the registration isn't even getting that far yet).
