Mitel 3300 - MCD 6 - 5312's
I have a line key programmed on a master phone. On a few extensions I then have a secreterial button programmed for it. This was set up some time ago. I still have my notes for it. I now wish to remove it all. I have removed all the scretarial buttons (or so I thought) that I had noted down so that I could delete the original line key. It seems though that there is still at least one extension that has a secretarial button though as I can't remove the original line key. We have approx 180 extensions. Is there any way to find which extension has the remaining secretarial button rather than me having to go through all 180 of them ? Thanks
