We are trying to make changes to our configuration, i.e. add some Hunt Groups, etc. We get as far as entering the change, and pressing the save icon. It doesn't matter which reboot mode we pick, we get a message saying the config is being sent to the control unit, but nothing happens. No changes are made. We are very new to this system and are totally stumped as to why we can't make changes to our configuration. Thanks for any help with this.
