Done quite a bit of searching but unable to find out how.
Basically I want the phone to show all 3 SIP extensions with their current status on the screen like the image below. Is there anyway to do that in FreePBX? If so, can you point me in the right direction.
Which phones? What have you tried so far? This capability is called BLF (Busy Lamp Field) - there should be settings in the phone’s own interface to specify the extensions you want to monitor.
