Introduction

In Chapter 2, Basic PBX Configuration, we learned how to add extensions, configure telephony cards and trunks, configure and control outbound and inbound routes from and to our PBX, set up an auto-attendant or IVR, and so on. With this, we have a fully functional PBX with few steps. In this chapter, we will explore more features to strengthen our Elastix Unified Communications System. These features will allow us to control the arrival of calls based on time, route calls to an extension or IVR, create ring groups and queues to attend to customers, and detect the CallerID of a call in order to route it or give it some special treatment. The recipes covered in this chapter will help readers to control incoming calls easily.
