| MWI light stuck on DTerm Series III
I have an NEC 2000 system with about 60 DTerm Series III phones. Occasionally, maybe once a month, 2 or 3 of the phones turn on their MWI and it will not go off. The voicemail system cannot turn it off, I cannot turn it off manually with a number plan command (CMD 20, Data=041), it almost seems like a diffferent feature turned the light on but I cannot find any reference to any such feature. The only way to turn off the light is to unprogram the phone and then re-program it and it will work normally again.
Also, one of the phones, it is permanently stuck on. Every time I reprogram the phone the light comes back on in a few seconds. I am 100% sure it is not the voicemail, I even disconnected the VM while testing it it still turned on. I even tried setting the phone to not support the MWI (CMD 13, YY=03) yet it still turns the light on.
If anybody could give me some insight into what to look for it would be greatly appreciated! |
