I'm sure I'm being completely stupid and have missed the relevent section of the Systems Administration Guide, but I'm trying to figure out how to re-program an extension to remove a line from one of its buttons (the line in question is a single analogue line, not a hunt group).
Feel free to just point me at the right docs for this (I'm not sure if the manuals are different around the world, but this is the UK version as sold by BT).
