when I connect to the NBN Connection Box (in UNI-V1) I have no dial tone
I wasn't aware that Optus provide phone service through the UNI-V1 port of the NBN box.
Have you signed up to a phone only plan with Optus (i.e. no NBN internet)?
Really? I have FTTH so I assumed that's where it plugs in. I've found wiring diagrams online that say that's where it is supposed to go. I haven't tried my modem yet as I have that up high in a cupboard but that'll be the next point of call if I can't get a solution
Yep, because they have to fork over more $ to NBN.

Not all phone providers support UNI-V, but everyone gets the same NBN hardware.

If they sent you modem then that's what you need to use.
