What is the Custom Extensions Module used for?

The Custom Extensions module provides you with a facility to register any custom extensions or feature codes that you have created in a custom script or dialplan and when the PBX doesn't otherwise know about them. This allows makes the Extension Registry to be aware of your own extensions so it can detect conflicts or report back information about your custom extensions to other modules that may make use of the information. Also, to keep this helps prevent you from using that creating a duplicate extension number somewhere else in the PBX.


The custom extensions module registers  extensions extensions used in your own custom applications so to ensure they don't conflict with other FreePBX PBX Modules.
