Hi we use Mitel 3300 MXe III and all out ONS ports (1,2,3,4) are already in use (LS 1,2,3,4,5,6 are unused)
I would like to add another analog line but it require another hardware.
The Analog Services Unit II + 3300 24 Port ONSP Card will probably do the job, but do you know something smaller an cheaper because I don't believe I use 24 analog ports ever.
