Installed a doorphone on a BCM 50 rls3.1. New doorphone NT8B79FE6. Button on doorphone is lite, push button and you get tone in speaker. Cannot access programming (feature 9*4). It tells me "inactive feature". Go into maintenance and the port shows "idle", device says "doorphone". Dial the extension number it says "not in service". It's driving me crazy !!!!
