I have got a cisco 7970 running Sip, working ok in regards to calls via 3cx.
One problem the brightness is only half way. I have changed settings to max on the phone but still its in low power mode.
Its plugged in with a Cp-pwr-cube3, I was under the impression that POE will force it to run in half brightness mode. As i am using the power cube this has got me stumped.
I have also tried adjusting the power saving feature in the config file, the screen will go into sleep mode etc but brightness is the problem.
