It sounds like it is a Vodavi infinite phone. Unless the system is running with infinite software, the phone won't work. Any chance you can find out what the model number is from the KSU? If it is one of their typical systems, the software version would also help us to help you. This can be obtained by dialing 605 from any display phone and recording the information that shows up on the display.
