Gspeakfreely is a VoIP system with a flexible
component system. It implements a set of audio
processing components which can be connected to
each other or mixed together. The most important
components are net in/output, which implement VoIP
functionality and the OSS-DSP in/output component.
Additionally there is a ISDN in/output component
that allows making actual phone connections, and a
file input component that can also play Internet
radio streams. Also included is a fading plugin,
that can for example fade incoming calls into your
music. New components can be developed for
specific purposes, and combined with existing ones.
