Changes

[https://freeswitch.com/ FreeSWITCH] is a voice service that can be used with [http://opensimulator.org/wiki/Main_Page 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 not complete, the compilation works, and the plugin states it's active in the console. Additionally in the viewer in the voice preferences voice can be tested successfully. However, neither local nor IM voice chat buttons are enabled.
