[OpenSIPS-Users] Permission module use .

[Surabhi Garg]

Hi  Sasmita,

Yes, permission module could be used for this. The permission module
provides function *"allow_registe*r*()"* which can be used in the
configuration script before saving the contact in your OpenSIPS
configuration file.

Below are the steps:

   - Create a *"register.deny" *file (this contains the details of IP
   addresses you'd like to block). Also, you could create *"register.allow"
   *file (this contains the details of IP addresses which will be always
   allowed).
   - Add *allow_register() *in your OpenSIPS configuration file as shown
   below in sample.


*NOTE: Sample of register.allow & register.deny file will be present in the
source code directory like /home/xxx/opensips/module/permissions/config/
for instance. You could refer them.*
*OpenSIPS configuration snippet for blocking IP:*

 if (is_method("REGISTER"))
        {
                if
(allow_register("/usr/local/etc/opensips/register.allow",
"/usr/local/etc/opensips/register.deny")) {
                        if (!save("location"))
                                sl_reply_error();
                } else  {
                        sl_send_reply("403", "Forbidden");
                };

                exit;
        }


*IMPORTANT: I'm assuming here that you'll be getting OpenSIPS own domain
address in the Contact. As far I know if you use OpenSIPS in proxy mode it
won't provide it's address in Contact header by default. This may happen if
OpenSIPS being used in B2BUA mode. *
