I have a 6942 given to me, but when power is applied (via POE or power adapter) all the lights flash then the "Speaker" light comes on and that's the way it stays. I tried powering up holding the # key, but still the same symptom. 123456789*0# will not do anything either. There is no display, just the speaker light is on. Is the phone dead?
