I have an old NuTone PTX-1200 home PBX (2x12) that has worked well for years. Unfortunately, it was designed before Caller ID (and other popular new phone company features) and it will not pass the signal.
Now, as I understand it, CID sends the info on a data burst before the phone rings for the first time. My idea is this: to build a device that will monitor the main phone line, sense the CID data burst and will "inject" it on the line(s) to the phone(s) without going off-hook and preventing the PBX from handling the call. Each phone extension line (which normally is connected just to a card inside the PTX-1200) would also be connected to this device.
Does this sound feasible? Has anyone heard of the existence of a device like this?
