[Serusers] Accept invite only for registered users

[E. Versaevel]

You are only checking here if the user has SIP REGISTERED a UserAgent to
your server, not if the user had a valid username/password.
You should check with proxy_challenge (which generates a SIP/2.0 407 Proxy
Authorization required message) and only if it is an outbound request
(domain not served by your proxy, otherwise your users can't be called).

So your code would become something like:

# check if it's an outbound request for a domain not on this proxy
if (method=="INVITE" && uri !=myself) 
{

	#check to see if there are usercredentials (and if they are OK)
	If(!proxy_authorize("yourdomain", "subscriber"))
	{
		#no or wrong credentials, challenge the user
		Proxy_challenge("yourdomain","0");
		Break;
	}
# accept call and goto route 3
route(3);
}


Kind regards,

E. Versaevel






Well, what I really want is something like:

if (method=="INVITE") {
# check if from_user 'caller' are successfully registered in my proxy
 if (!lookup('%from_user% in location table')) {

     sl_send_reply(404,"Not authorized - You must bu registered to use
this proxy");
     break;
 }
# accept call
route(3);
}

Well 'ALL CALLS' in my proxy, must to be authenticated...

I don't if this test must to be done on 'invite' or maybe in route(3)
subroutine.

Regards.
