Moved public API classes into namespace tgvoip (CVoIPController -> tgvoip::VoIPController, CVoIPServerConfig -> tgvoip::ServerConfig) Endpoint is now a class instead of a struct; also, IP addresses are now wrapped into objects instead of relying on in_addr and in6_addr Full Windows port (Win32 threading + Winsock + WaveOut/WaveIn) Added support for ALSA audio I/O on Linux (closes #2) Abstracted away low-level networking to make it more portable Minor bugfixes
