License Update

License installation and update is done from the menu “System -> License”. 
Even if the license is already installed, you can upload a new license or verify your current license details there.

If you want to install the license for the first time or update to a new license, 

  • click“Choose File” and upload the.tar.gz license file provided by Sangoma. Then click “Upload”.
  • After uploading the license you will see the details of the uploaded license.



In this example, the license has a limit of 500 sessions
Different vendors have a different concept of what a “session” is. 
With Sangoma SBC things are much simpler. One session is one call. 

Sangoma’s NetBorder Session Controller do not require extra licensing for registered peers (SIPREGISTER message), SIP trunks or any other SIP entity.

In case of upgrades, of expansions please contact Sangoma Sales.
