Description
FreePBX phone extensions are actually made up of two components which are not visible when you are running in the FreePBX default Extensions mode. However, each extension is made up of one FreePBX User and then zero or more devices. The number that you dial the user at is always the same and will typically be referred to as their extension number. That extension number can then be permanently associated with a fixed device in addition to being able to login to an adhoc device. Once logged into a device, it becomes that user's extension until logged off. It will use their CID and Outbound CID, DID's associated with that user will be routed to that device (and any others they are associated with), Voicemail MWI will display on that device, etc.
