Does anyone know what M39XX firmware comes standard on what system Rls? I have 4.5, 5.0, 5.5, 5.0, & 7.0, but I don't know what firmware comes standard for the M39XX phones. What I am trying to do is locate at least F/W 8.9 for the M3903, then put the system together and push the firmware down to a bunch of phones. I have an ancient 24.5 loaded at the moment, but the firmware on that system is ancient as well. If anyone can lend some advice I would greatly appreciate it.
