With the advent of our PBX service on sat5, we need a numbering plan!

• 1 XXXX - “User” numbers, each user can have one or more numbers from here, for use with actual phones
• 2 XXXX - “User Service” numbers, redial, voicemail, etc
• 3 XXXX - “Global Service” numbers, numbers that do something useful/fun
• 8 … - “Dial-out” prefix, to access other trunked PBXs
• others - Reserved

I felt like it. Four digits after each prefix will probably (i say) be enough. Though there is nothing stopping us from using variable-length numbers in the future.
