Hi Jim, not sure, but I never received them, and I sent another one to ask about commercial terms, I am not knocking Vivox, I just never got a reply, may be it got lost. I wanted to push ahead with what I was doing, and after waiting a few days just assumed there would be no response coming. I sent my emails to opensim@vixox.com assume that's the correct address?
Anyway, its by the by now as I am using TeamSpeak, and so far everyone on my grid that has used it, likes it. The more options for voice in OpenSim the better. I wish Vivox well and hope you can come up with a reasonable commercial solution for smaller grids. I am paying USD$29 a year for 32 simultaneous voice connections, that goes up to USD$55 a year for 64 slots, I think that is reasonable for a small grid.
