--- title: "On-Call Rosters" --- # On-Call Rosters > >

The On-Call Roster defines user groups to be notified when an alarm occurs. Each group includes a list of users in a specific order. Alarm pipeline notification blocks must choose an on-call roster that identifies the users to notify for that notification block. When notifications are sent out by a pipeline, all users on the roster will be notified, except for any off shift (see [schedules](platform/alarming/alarming-schedules/alarming-schedules.md)). On-Call Rosters are statically defined, in that they can't be modified from a pipeline. However a [calculated roster](ignition-modules/alarm-notification/alarm-notification-pipelines/pipeline-blocks/notification-block.md) can be created on demand on a notification block. ## Create and Manage an On-Call Roster 1. Go to the **Services** section of the Gateway Webpage. 2. Click **Alarming** > **Rosters**. ![](2020-04-03_16-19-22.png) 3. Click on **Create Alarm Roster**. ![](2020-04-03_16-21-42.png) 4.

Click **Save Changes**. ## Manage the Roster from the Client Roster management also can take place from within a Vision Client. 1. Open your project in the **Designer** and navigate to a window the client has access to. If this is a new window, you will have to add it to your navigation. 2. From the Component Palette, drag and drop a **Roster Management** component in your design window. ![](2020-08-17_14-47-06.png) 3. If you have more than one user source, go to the Property Editor and enter the one you want to be used by the roster in the **User Source** property. 4. **Save** your project. 5. To interact with the roster, either launch your Vision Client or put your Designer into Preview mode. 6. To edit the roster, double-click any where on the roster or click the **Edit** ![]() icon in the upper right. ![](2020-08-17_14-59-11.png) 7.
