The 'roll back' procedures on this page describe how to restore your previous version of Sonus SBC 1000/2000 in the unlikely event that you encounter an issue with your Sonus SBC 1000/2000 upgrade.
Before you begin
Prior to rolling back your Sonus SBC 1000/2000 upgrade, ensure that you have a backup of your Sonus SBC 1000/2000 data for the version you intend to roll back to.

Refer to the appropriate upgrade instructions below for your Sonus SBC 1000/2000 hardware configuration:

The instructions in this section may be best coordinated with your Sonus service representative.

- Remotely login to the ASM via Remote Desktop.
- Manually uninstall the current Sonus SBC 1000/2000 Communication Service from the Programs and Features via the Control Panel.
- From the Sonus SBC 1000-2000 Download Center, download the Sonus SBC 1000/2000 Communication Service
.zipfile for the version that you are downgrading to.

- Copy the
Setup.msionto a local folder directly onto the ASM.
- Launch the installer and proceed with the installation wizard.
- To ensure the Sonus SBC 1000/2000 Communication Service was properly updated, verify the Sonus SBC 1000/2000 Communication Service Version has changed to the intended version.
Important ASM Note
If you are downgrading from 2.0.x (or later) to → 1.3.x (or earlier), all disabled Network Adapters on the ASM must be enabled. This is because the 2.0.x (or later) upgrade disables one of the network adapters (by design), and it must be re-enabled if you're downgrading to 1.3.x (or earlier).
- From the Start menu - type View network connections and select it
- You will find at least one disabled network adapter. Enable it as shown below:
Once the network adapter is enabled, you must set the necessary permissions to allow the downgraded Sonus SBC 1000/2000 Communication Service to Install ASM packages via the Sonus SBC 1000/2000 WebUI.
- From the Start menu - type Command Prompt and select it
Enter (or paste in) the following commands - the order is important:
The results should appear like so:
You now may proceed with rolling back the Sonus SBC 1000/2000 software version, follow the instructions below
Rollback the Sonus SBC 1000/2000 Software
The Sonus SBC 1000/2000 keeps its system software (firmware) in containers known as "Application Partitions". There are two application partitions, one of which is Active. When the Sonus SBC 1000/2000 system is operational, it is running off of the Active Partition, and the remaining (inactive) partition serves as a spare.
You can rollback to the previous Sonus SBC 1000/2000 version stored in the inactive partition:
- To rollback the Sonus SBC 1000/2000 Software, simply activate the inactive partition.
- Verify that you are booting from the new partition either by checking the active partition, or by Viewing the Software Version and Hardware ID.
- Restore the backup configuration data associated with the Sonus SBC 1000/2000 version you have downgraded to.
This completes the rollback procedure.
