Overview

The SBC SWe Lite is a Microsoft-certified virtualized Session Border Controller (SBC) designed to provide small and mid-sized businesses interworking, security, and survivability for unified communications. The SWe Lite is available for deployment in Azure Marketplace as a BYOL (Bring Your Own License); it will be created as a virtual machine (VM) hosted in Azure. 

These instructions include how to configure and deploy the SBC SWe Lite in Microsoft Azure cloud. All configuration commands are via Azure Portal; the equivalent Powershell configuration comments are referenced here: Using Powershell Commands to Add Resource Groups and Virtual Networks in Azure.
