Remove DIT on 1 extension/phone

[philly212]

I have an Electra Elite system. All phones appear to be setup with DIT. They all ring when an incoming call is placed. I want to be able to remove this ringing for one extension.

What flashes when the phone rings? You say the phones are "DIT" but that term is usually associated to trunks.
Do the trunks appear on the phones?
Check MB 3-42 and see where each trunk is going to.

If it is just amatter of all extensions ringing on incomming calls, then MB 4-01 is where you need to make the changes. Green=Immediate Red=delay Dark=no Ring. Also in 4-02 you set Night ringing.
