I am using 3com POE injectors behind a gigabit switch, the POE injector is a 10/100 device and my phones are 10/100/1000, the phones will NOT link up. When I remove the POE injector from the equation, and use "wall wart" transformers to power the phones, all is good, phones link and talk to my VOIP PBX and the world! Anyone run into this before? Any solution or ideas?
