Onwards

So now our campsite has been packed away and it is time for the next part of our journey to begin, for those first purposeful steps to be taken towards the summit. We will start in Chapter 1 by looking at the heart of any Asterisk system, the dialplan. You will already have significant knowledge in this area, but we are about to show you some of the techniques that are used in systems with thousands of extensions that handle many tens of thousands of calls per day. Without these techniques, a dialplan can become an unholy mess as system size increases. However, using these techniques will ensure that complexity is avoided and performance is maintained.
