The firmware is loaded onto the SSC card then pushed to the phones, I am sure it all depends on the release of the CS1000 software, but I have all the releases so I am not concerned about that, I am just lacking these specific firmware releases for these phones. I am thinking 9.4 is fairly newish and none of my systems have it. I am not the end user, I am just a middle man in a warehouse that a customer asked to load a specific firmware. About a year ago we were able to load 9.0 onto a system and push it out to the phones successfully, I am just not sure how far up the line 9.4 is and if there is a copy of the firmware outside of the official Avaya channel.
