Use the System window to take an SBC SWe cloud node out of service and to specify how you want to manage any existing call traffic on the node. To optimize the use of resources in cloud environments, you might choose to remove an SBC instance when the call volume is low. For SBC SWe cloud deployments on OpenStack, the SBC provides options you can configure to minimize the impact on existing calls and registrations by allowing a period of time for existing calls to "dry up" when you are taking an instance out of service. This window is only available on SWe cloud systems.
This feature is not available on M-SBC nodes.
From the SBC main screen, go to All > Global > System. The System window opens with the System options available for editing.
Use the following table to configure the options then click Save.
