You can also override (but not enable/disable) forwarding a phone by assigning the number to a DSS key and DO NOT activeate the feature "DSS without feature override" on the phone that has the DSS key. I call it the "god button" and have to use it to call senior leaders who have their phone set to never ring in order to confer with them about something the asked me to do, in real time, not swapping voicemails. If you do not protect the DSS key then the number can be changed at will (usually) by holding down the button.
I have had this same problem with my 4 AC-Win consoles, and I have developed some strategies for avoiding it. First, if you need to exit AC-Win use the File - Exit command from the top menu as that will allow AC-Win to properly communicate it is terminating. If you need to reboot an AC-Win PC due to windows updates or whatever, after properly exiting AC-Win and doing what you have to do, use the "Shutdown" command and NOT the "Reboot" command. Leave the PC off for 1 - 2 minutes and then restart it. That gives the licensing server the opportunity to notice that console disappeared and make that license available again for when that console goes to authenticate again.
Dumping AC-Win by "X-ing out" of the application is not good practice and can lead to this problem.
I also suggest to my users that when you exit AC-Win that you DO NOT save the workspace - ever. I suggest that if they make changes to the console buttons, or the configuration that you Immediately save the workspace "File - Save Workspace" after making your changes so that you specifically know you did something you want to save. Most definietley Never save the workspace if you are having problems because that will usually also save the problem forever. If you exit without saving the workspace then you should be able to re-start the application and the workspace that worked when you started it the last time will load again and you should be good to go.
