The problem is that your company is a cheapskate outfit just buy a separate ip based phone and plug that into the other port at your desk - oh you did follow standard practice and pull two cat5's to every desk.
Not sure if we have 2 drops per cube. There's 2 ports, but I don't know if they're active, cabled but not hooked up to a switch, or not even run to the cube. Haven't bothered to test because our old Cisco phones had a pass-through port, and now I only have 1 device that could use an ethernet port.
