Does anyone know if a system exists where I can link two phones together other than wirelessly or by a long extension wire/cable? My setup is such that I have a two handpiece phone but for various reasons the secondary handpiece is struggling to make proper contact with the base (primary) handpiece (distance and walls, etc.). I have the same problem with a laptop used wirelessly at the other end of my house. I've solved the laptop problem by using a Belkin arrangement which basically couples the computers together via the mains wiring, and this works very well. I wonder whether there's something similar which would work for phones.
