Blink

Blink is a mature open source real-time communication application that can be used on different operating systems, based on the IETF SIP standard. It offers audio, video, instant messaging and desktop sharing. It supports end-to-end asynchronous messaging and end-to-end encryption which works both online (OTR) and offline (OpenPGP).
