I had an older Nortel conf phone on a BCM400 rls 3.6 that shows up in programming as a M7100. It still works on the new 450 but I'm unable to use the feature key. If I hit just the feature key and a code, nothing happens. If I go off hook and hit the feature key I get a uh-oh tone from the phone on some codes and some just allow me to keep inputting digits but don't actually do anything. I specifically want to use F0 but can't get it to work. Think I'll have to replace it with a newer model? I never tried to use any features on the 400 so I don't know if it worked or not.
