This is just a quick note that there will be a voice-over-IP enabled OpenSimulator available as a public image on EC2 within the next days.
After some (well, a lot!) of tweaking we are finishing this up right now and it works very well already. The notion is to have a (nearly) out-of-the box solution for virtual conferences with extranet or intranet like character. It tries to save you from the hassle of finding sources, libraries and configurations.
You simply start the image into the cloud and associate an elastic IP to it. Then after you go through the standard OpenSim setup, the voice support is there – you only need to enter the IP address or domain name once in the setup. Then some scripts configure of Freeswitch and OpenSim correctly according to the Amazon Elastic IP provided.
As I said it is as good as ready so if anybody wants to give it a try early then leave a note.
