Some Application software changes are delivered as patch, which is substantially smaller than a firmware upgrade. A Patch is always based on specific Major or Minor release, so you must apply patch only to the specific Base Software Version for which it is designed. Unlike Sonus SBC 1000/2000 software/firmware versions, patches can be applied to currently active partition or the non-active application partition. All system configuration is preserved when you apply a Patch.
If you uploaded the patch to the currently active partition, the system restarts the patched components. Depending on which components were patched, this process may disrupt currently active calls. Sonus recommends that you only apply patches to inactive partitions or to active partitions during a planned service outage.
To upload a Sonus SBC 1000/2000 firmware patch:
In the left navigation pane, go to System > Software Management > Application Partitions.
Application Partitions
Click the Upload Patch link - a popup window will appear:
Upload Patch
Depending on the size of the patch, it may take a few minutes to update the Sonus SBC 1000/2000 system.
