We use “Endpoint Manager for UCP” and have allowed users to change their phone buttons. But if they make modifications and want to save, the “apply” button doesn’ t do anything. We tried multiple browsers like IE, Mozilla Firefox, etc… same issue.
We use the following module versions:
FreePBX Framework 18.104.22.168
User Control Panel 22.214.171.124
Endpoint Manager 126.96.36.199
