mdt-daniel & Gumshoe Thank you for reporting the issue, apparently I was checking on a different version.
Try the following command, that will bring up the Endpoint Configurator under the PBX menu and let us know:
issabel-menumerge /usr/share/issabel/module_installer/issabel-endpointconfig2-4.0.0-1/menu.xml
Thanks! The dev tem has been notified about this.
