Rob solved a phone ringing problem in cubicle land “I work in an office of several cubicles. Often someone is on the other side of the room, and a phone rings. Who’s phone is it? All the phones sound the same, and the cubicle walls block line-of-sight to the indicator light on the phone. That is, unless it’s remotely located in a picture of a deer, up where I can see it. Now, with Caller Eye Deer, I know whether or not to run across the room.” Link.
