<div dir="ltr"><br><div class="gmail_extra">Hi Sasmita,<br><br></div><div class="gmail_extra">Yes, permission module could be used for this. The permission module provides function <b>"allow_registe</b>r<b>()"</b> which can be used in the configuration script before saving the contact in your OpenSIPS configuration file. <br><br>Below are the steps:<br><ul><li>Create a <b>"register.deny" </b>file (this contains the details of IP addresses you'd like to block). Also, you could create <b>"register.allow" </b>file (this contains the details of IP addresses which will be always allowed).<br></li><li>Add <b>allow_register() </b>in your OpenSIPS configuration file as shown below in sample.<br></li></ul><i><u><b>NOTE:</b></u> Sample of register.allow & register.deny file will be present in the source code directory like /home/xxx/opensips/module/permissions/config/ for instance.
