KDE Telepathy

KDE Telepathy is an instant messaging (IM) and voice over IP (VoIP) client which supports text, voice, video, file transfers, and inter-application communication over various IM protocols. It uses the Telepathy framework as its back-end. It is the slated replacement for Kopete, and its main focus is the integration between different components of the KDE Software Compilation that may benefit from real-time communication and collaboration features.
