TNG and Mitel: all my calls cost at zero

I am running TNG
All my calls cost at zero.

I have a Mitel PABX.

On the Call List page all calls have zero cost.
My trunk/lines all shows as INTERNAL.


  • Start the TNG service.

  • Make an outgoing test call and ensure it has a duration.

  • Check that the trunk shows as Y9999 and has a cost.
