WARNING: If NSC does not start after an upgrade, this is probably due to old DSP module firmware.
The following information applies if you are updating SBC software version from 2.0.X-XXX->2.1.X-XXX.
If you are simply updating from version 2.1.X-XXX->2.1.X-XXX then use the standard update procedure and navigate away from this page
Follow the steps below to update from 2.0.X-XXX->2.1.X-XXX:
Create a backup of your entire SBC by navigating to the following location, from the SBC webGUI:

Updating Software release
Because there are many signification improvements in 2.1.X-XXX release versions (when compared to a 2.0.X-XXX release) the update procedure involves a complete installation of the ISO (which will reformat the current SBC software).
*Please verify that you have created your SBC backup, and saved it to a safe location off the SBC server
- Navigate to the SBC Download page to download the new ISO
From the software release versions available in the above link, right-click on the iso link from the first row in the Current Release table, and save the ISO image to a local server
the Maintenance release table can be ignored. This table is used for pre-2.1 release versions only
- Burn the downloaded ISO image onto a DVD disk or USB stick
- Insert USB stick into one of the SBC USB ports or use a DVD USB adapter, reboot and select the proper boot device in the BIOS.
(the steps that follow are standard ISO installation screens, which will be skipped here)
* Please remember the login credentials and IP information you have enter here as they will be used to log into your SBC after update.
- Once the update is complete you can now log into the SBC webGUI:
- When logged in you will notice a the following screen indicating fresh installation
- To view the software release version of the SBC, navigate to:

New Dialplan features
One of the significant changes in SBC software release 2.1 and above is the all new GUI based dialplan.
Below is a screenshot of the dialplan section after the fresh installation:
As seen the diagram above, the dialplan is split into two sections:
- Basic Call Routing: GUI Based Dialplan creation. Complete dialplan is configured by selecting category drop down selections
- Advanced Call Routing: Text based dialplan creation. For dialplan editing not available via the Basic Call routing. This is used to compliment the main dialplan that resides under the Basic Call Routing section.
When configuring the dialplan in SBC 2.1 and above, you should always use the GUI based Basic Call Routing. However, when you restore your SBC configuration (from backup file) from software release below to 2.1, the entire dialplan will restore to the Advanced Call Routing section and will leave the Basic Call Routing empty. If you decide to modify your dialplan in the future you will need to continue using the Advanced Call Routingsection and leave the Basic Call Routing empty.
If you decide that you want to use the new GUI based dial plan , you will need to reconfigured everything via Basic Call Routing dial plan section, then edit all your SIP profiles to use the new dial plans (replacing the old ones).
