Technical

Voice in Second Life uses Vivox technology that is based on RTP (using the oRTP library), SIP (using the amsip library from Antisip), OpenAL, TinyXPath, OpenSSL, and libcurl for the transmission of voice data. The positional 3D audio is achieved with technology from DiamondWare. These technologies are contained in external daemon software that is started and stopped by the Second Life client.
