Free Switch

Introduction

FreeSWITCH is a voice service that can be used with Opensimulator. Until recently it has been a little-used option; however, with the announcement that Vivox support for opensimulator is coming to an end, it is one of the alternative options.

This page is aimed at adding to the information available for both getting a working version of FreeSwitch and configuring it for opensimulator. At the time of writing the latest release is 10.6.
