I have a RCA ViSYS 4 line multi - handset office system model 25450 and I'm trying to make a headset I got work on it. Unfortunately, it's not working. The headset button isn't doing anything and the manual that came with the phone doesn't say very much on how to make it work. If you could tell me how to get it working it would be greatly appreciated.
