Offline Mode

Last Updated : Aug 30, 2026 |
By default, Web Manager operates in real time and configuration changes are applied to the IP Office system immediately. However, some settings can only be changed in offline mode. Web manager will indicate when that is the case.
In this mode, you can make multiple changes to the configuration and then apply them using the Save to IP Office action. Depending on the settings changed, this may cause a reboot of the IP Office service and ends all calls currently in progress.

Using Offline Mode

To select offline mode, click Offline Mode. Once in Offline Mode:
  • The Offline Mode changes to Save to IP Office.
  • The Save to IP Office option is also available above the menu bar.

Saving Setting in Offline Mode

After clicking Save to IP Office, web manager displays a save dialog with the following settings. Configure the menu as required and click OK.
Setting
Description
IP Office
Select the system to which settings should be saved. In a Server Edition network, more than one server may be shown.
Change Mode
Select the method of saving:
  • Merge - This method is automatically selected if none of the configuration changes made require a system reboot. If this method is used for a configuration that includes changes that do require a reboot, those changes are not applied until the system is manually rebooted.
  • Immediate - This method saves the new configuration changes and then restarts the system. Any current calls and services in progress are ended. This method is automatically selected if any of the changes made so far require a reboot before they are applied to the system.
  • Free - This method allows the Incoming Call Barring and Outgoing Call Barring options to be used. The system reboots when the criteria for the selected options are matched.
  • Timed (HH:MM) - This method reboots the system at the selected time. It can also be used with the call barring options to only reboot after the set time when the selected options are matched.
Reboot Time
Set the time for the reboot if Timed (HH:MM) is the selected save method.
Incoming Call Bar
This option can be used with the Free and Timed reboot methods. When selected, the system bars any further incoming calls. However, it allows existing calls to continue until they are ended.
Outgoing Call Bar
Outgoing Call Barring - This option can be used with the Free and Timed reboot methods. When selected, the system bars any further outgoing calls. However, it allows existing calls to continue until they are ended.
Other:
  • This option also bars the making of emergency calls. Therefore, it should be used with caution.
