I am trying to upgrade a 57I CT. Currently running 2.1.0.2145. I have tried using the web browser and get "fail to upgrade"
Tried TFTP server and fails as well. I am using Solar Winds TFTP software. Could someone help. I think I followed all of the steps.
Dose anyone have Aastra phones working on a 3cx?
