Although Asterisk has no such requirement, these extensions should probably all have the same length to give comfort to our users. We must determine the length that we will use for all of our extensions. When creating extensions, it is often advantageous to group certain extensions together. For example, all sales extensions could be in the 200's, support in the 300's, management in the 100's, etc. Or we could go further and say that all first-tier support will be in the 3100's, the second-tier support will be in 3200's, third-tier support will be 3300's, and so on.

We get to choose how to use Asterisk's power and flexibility to meet our real-world needs. While the order in which we proceed makes sense, it is not necessary that we follow it precisely. We can configure the pieces in any order we want. The only issue we may encounter is that if we have not completely configured one part of Asterisk, the PBX may not start, or may start without full capabilities. This is not a real problem, as we are still configuring and will be testing our PBX later. Thus, if we become unsure about how to proceed in one section, it may be best to move on, and configure the next part.
