[SR-Users] Call forwarding from external did

[arun Jayaprakash]

Thanks Fred, attached is the portion of the config file where I am doing the check. Also, can you let me know what you mean by "trying any number to your system"? Thank you.

if (uri=~"sip:1[2-9][0-9]+ at .*") {
                                                if (!is_user_in("From", "ld") && !is_user_in("To", "ld")) {
                                              #Initally the above line was if (!is_user_in("From", "ld") )
                                                xlog("LOG: PSTN call but user don't have permissions\n");
                                sl_send_reply("403", "No permission for long dist calls_here_is_the error");
                                exit;
                        }
                }
                
        }

        # only local users allowed to call
#        if((from_uri!=myself)) {
#               sl_send_reply("403", "Not Allowed");
#               exit;
        # }


Regards,
Arun

In short, yes, it is risky-- but in honesty, noone can tell from just 
that portion of the config.

You can test this perhaps by trying any number to your system. Is it 
also being forwarded?

A good way is to add a flag and check for the presence of that flag if 
allowing a non-registered user to make an outside call.
