Re: [Serusers] Ser 0.9.0 and Cisco Voice Gateway - sr-users

21 Apr 2005

Hi Steve!

Now it works properly. Like you wrote the port command
was missed in the dial peer.

dial-peer voice 1 pots
 description Default-Dial-peer fuer ausgehende Anrufe
 preference 3
 service session
 max-conn 25
 destination-pattern 0T
 progress_ind alert enable 8
 direct-inward-dial
 port 0/0/1:15

Now I have activated the www_authorize section.

# Uncomment this if you want to use digest authentication
                        if (!www_authorize("netuse.de", "subscriber"))
{
                         www_challenge("netuse.de", "1");
                                break;
                        };

On my cisco I see following when I enable the ccsip debugging:

It looks like the cisco tries to registering to the server, but the
server decline this.

How can I enable the registering of my gateway in ser, without to disable
the www_authorize ?

 Ahmad

 Hi!

 Can I ask you some questions?
How do I know, that my ser server only act as registrar and
redirect Server ? With redirect I mean, any other calls, which
starts with 0, redirect to the gateway. 

I'm not sure I understand. Are you concerned about people outside
of your user community routing calls through your proxy and out to the
PSTN? If so then you need to use check_from and check_to to
determine if the caller is authenticated to your proxy. 
I have following line in ser.cfg
t_relay_to_udp("192.168.254.203", "5060");
when I understand you right, then I have to change this paramater to
sl_relay_to_udp("192.168.254.203", "5060");
  No, the t_relay is fine.

 This would mean stateless forwarding to this
gateway ?
correct ?

Regars,
 Ahmad
