Can someone use the 'Yealink Configuration Generator Tool' to edit extensions MACADDRESS.CFG files in the servers provisioning folder and push changes to the phones? In my mind, this should work. I have tested this on a few handsets and have not been able to see my changes on the phone. Am I missing a step? Editing the wrong file? Forgetting something? I have tried searching for this answer, but keep finding regular information about provisioning templates or out dated information. What is the best way to manage the buttons and settings that you can't manage via the 3CX console, if this tool will not work? Thanks for your help.
