We were recently forced to upgrade the software on our 3300, and unfortunately, that created a ripple... The new update rendered 9 of our phones (5235's) useless, as they are no longer supported! Unfortunately, these were our "Executive" phones, and two of them had PKMs on them. I obtained replacement phones (now 5330's) and the updated PKM IM unit (50005662) that plugs into the backs of them. Unfortunately, I still get no power to the PKMs. I located a PDF that seems to show a small 4-wire ribbon cable that plugs into the circuit board on the phone, and also into the IM. I assume this is where the power comes from?
Anyone have any leads on where to find these cables? The connectors are different on each end, and I have been unable to locate a seller for the cables.
