Normally, we use 8324SJ or 8212S phones on our system. We ordered some more 8212S (from a discount place) and were "upgraded" to 8412S large lcd display phones.
The phone works, but the LCD flashes No Communication, a copyright, a date code, and a firmware number.
VMMI shows the Phone Type to be an Impact SCS 12 Line Large LCD. That seems right. It's not actually on the list if I try and change it manually, but it reverts to that selection if I quit or disconnect/reconnect.
I guess the question is why does No Communication flash/blink. For that matter, the LCD never changes when using the phone.
Thanks,
Bob
