Hi, my customer is running a real old version of Communication Manager (1.3.0, to be exact). I connected a 4620SWIP phone, received the proper firmware upgrades from my TFTP server, yet the phone has no LCD display, although it has dialtone and sends the correct extension when I call another station on their switch.
Furthermore, I know their isn't anything wrong with the phone itself because I connected it to an IP Office and the display showed just fine.
I also checked Avaya's compatibility matrix and couldn't even find any detailed info on CM 1.3.0.
Any help will be greatly appreciated!
