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.

System (Global) Parameters
Parameter | Description |
---|---|
Mode | Use this parameter to set the system state. The options are:
|
Action | Use this parameter to specify how the SBC handles existing calls when the Mode is set to Out Of Service. The following options are available:
|
Dry Up Timeout | This option specifies the time interval (in minutes) the SBC allows for existing calls to complete before the SBC transitions fully to the Out Of Service state. Once set, you cannot change the value of the running timer unless you change the system back to In Service mode. Changing the value once a dry up action is in progress has no effect on the system. The supported range is 15 minutes to 1440 minutes (1 day). The default is 120 minutes. |
