FreeSWITCH, OpenSim and the G722.1C codec

Kai Ludwig has recently left a very valuable comment (thank you, Kai):

Actually the new FreeSwitch siren14 codec has never been used with SLVoice! Everybody having voicechat with OpenSim is using PCMU without knowing it. Kai Ludvig

I didn’t realize that at first either, but after he pointed this out, I started looking for a way to enable siren14. I haven’t really come up with a way to use the SLVoice.exe included with the SecondLife viewer, rather, I modified the voipforvw codes to support it. Voice quality is now way better than the stock PCMU. Connecting to
