Hello, Granted access to a extension of a Group in 3CX PBX can be expanded. Now, in version V.15, only the following options are visible : Extensions, Groups and Call Reported. In this case the extension has no rights to General System Administration. It will be a good idea the options : Contacts, Call log, rights to edit the Group /add or delete group members/ to be managed by the manager of the Group. Thank you!
