Try something like this:

if (method=="INVITE")
{
   if (!www_authorize("xxx.org", "subscriber")) {
       www_challenge("xxx.org", "0");
       break;
   };
   if (!check_from()) {
 	sl_send_reply("403", "Only registered users are allowed");
     	break;
   };

};

 Now we understand what the what the message means after
reading the message
a few times.  We are trying to do PSTN(as5300)  ---> ser  -----> pstn
(AS5300),  and to authorize the calling number (callerid) in the INVITE
message against URI table.  But check_from command needs to call
proxy_authorize, which it requires username and password. we setup the
configuration like this

if (method=="INVITE" & proxy_authorize("xxx.org",
"subscriber")
	if (!check_from()) {
 		sl_send_reply("403", "Only registered users are allowed");
     	break;
	}
}

Because cisco does not have sip password setting, so we have 

0(3173) check_username(): No authorized credentials found (error in scripts)
...
  0(3173) check_username(): Call {www,proxy}_authorize
before calling check_*
...
 function !

Does anyone has a solution?

Hello,
the last error message is self explanatory. You need to call either
www_authorize() or proxy_authorize() before calling check_from() because
this method compares the data from From header with what is in
credentials (response to a authentication challenge).

 Dear all,

We have configured Ser to check from username field to authorize user
“unknown”

if (!check_from()) {

sl_send_reply("403", "Only registered users are allowed");

break;

};

We have error message

0(2568) check_username(): No authorized credentials found (error in
scripts)

0(2568) check_username(): Call {www,proxy}_authorize before calling
check_* function !

We have “unknown” username entry in uri table.
