Summary

In this chapter, you have been provided information to understand OpenSIPS in terms of what OpenSIPS is, how to acquire OpenSIPS knowledge, when to use OpenSIPS, and who is using OpenSIPS. From the internal perspective, you learned the design/structure of OpenSIPS, such as what are the OpenSIPS modules and what they can provide.

With this better understating of OpenSIPS, in the next chapter, we will focus on using OpenSIPS and the scripting language and routing concepts.
