Overview of this book

OpenSIPS is a multifunctional, multipurpose signalling SIP server. SIP (Session Initiation Protocol) is nowadays the most important VoIP protocol and OpenSIPS is the open source leader in VoIP platforms based on SIP. OpenSIPS is used to set up SIP Proxy servers. The purpose of these servers is to receive, examine, and classify SIP requests. The whole telecommunication industry is changing to an IP environment, and telephony as we know it today will completely change in less than ten years. SIP is the protocol leading this disruptive revolution and it is one of the main protocols on next generation networks. While a VoIP provider is not the only kind of SIP infrastructure created using OpenSIPS, it is certainly one of the most difficult to implement. This book will give you a competitive edge by helping you to create a SIP infrastructure capable of handling tens of thousands of subscribers. Starting with an introduction to SIP and OpenSIPS, you will begin by installing and configuring OpenSIPS. You will be introduced to OpenSIPS Scripting language and OpenSIPS Routing concepts, followed by comprehensive coverage of Subscriber Management. Next, you will learn to install, configure, and customize the OpenSIPS control panel and explore dialplans and routing. You will discover how to manage the dialog module, accounting, NATTraversal, and other new SIP services. The final chapters of the book are dedicated to troubleshooting tools, SIP security, and advanced scenarios including TCP/TLS support, load balancing, asynchronous processing, and more. A fictional VoIP provider is used to explain OpenSIPS and by the end of the book, you will have a simple but complete system to run a VoIP provider.

Chapter 6. OpenSIPS Control Panel

In the previous chapter, you learned how to manage subscribers using a MySQL database. Now, we will need a tool to help users and administrators. Obviously, this tool has to be easier than opensipsctl. It is hard to manually manage thousands of users, so a user provisioning tool becomes very important for our process. In this chapter, we will see one of these tools called OpenSIPS control panel. We will see how to use some control panel modules in the next chapters when it is relevant.

In this chapter, we will cover the following topics:

  • Identifying why you need a user portal for administration

  • Installing the OpenSIPS control panel and its dependencies

  • Integrating the OpenSIPS control panel into Monit

  • Integrating a control panel to OpenSIPS using a FIFO file

  • Configuring administrator and module access

  • Adding and removing domains

  • Managing subscribers

  • Managing aliases

  • Managing the Access Control Lists (ACLs)

  • Managing permissions and IP authentication

  • Using OpenSIPS-CP...
