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...

Nick,
Any special reason why your're using port 5061? It's the port for sips
(sip over TLS), so maybe the client doesn't like that? Try 5060, maybe
that helps.
Beside that, can you ensure the client got that response? Any NAT in
between?

I was using 5061 because it's a VM running on the same server, and this
way I was able to filter the traffic when looking at the ngrep output...
I just got a mail from Xlite support they said the problem was probably
this: Mobilia SIP Server.
My server header/signature was confusing the clients, as soon as I
removed it, everything works perfectly... probably I need to learn a bit
more about what can go in headers.

Nick,
Ah, didn't see that from your dump. You have to set a Header-Name, like
"Server: Mobilia SIP Server", not just the value.

server_header = "Server: XXX SIP Server"
pls check this URL:
http://www.openser.org/dokuwiki/doku.php/core-cookbook:1.2.x#server_header
Please note that OpenSER will only write
My Company SIP Proxy.
into the header.
To add a valid Server: Header, use server_header="Server: My Company SIP Proxy",
this will add
Server: My Company SIP Proxy
I just trapped into this Problem with OpenSER 1.1.0 and Sipura Clients, Softphones work
correctly.
Best regards,
Gang Liu
