Put in a different system :-)
I got around to checking it and RTFM. 112 keeps the DSS from blinking on CF/DND per 1.1.70 of the OM. Since the extension is "busy" on incoming calls if it rings, you get a red light. I never noticed it before because we don't usually ring all phones or set up DSS buttons in our 824 applications. For fun, set 112 to enable, go to a phone and on the intercom press FWD 4#. You'll see what 112 does.
The solid red on incoming calls must be a feature, not a bug. It doesn't do that on my TAW or TDA.
