It is very hard to manage thousands of users manually, so a user-provisioning tool becomes very important in our process. In this article by Flavio E.Goncalves, we are going to see two of these tools—SerMyAdmin and OpenSIPS Control Panel (OpenSIPS-CP). SerMyAdmin is more focused on the administration of the users, while OpenSIPS-CP is excellent for monitoring and provisioning parameters to the system. By the end of this article, you will be able to: * Identify why you need a user portal for administration * Install SerMyAdmin and its dependencies * Configure resources such as administrator and user access * Add and remove domains * Customize the portal with the colors and logos of your company * Install and configure OpenSIPS Control Panel * Use opensips-cp for daily tasks
