Libgami is a cross-platform library for connections to the asterisk manager interface based on GObject and glib. It may be used from any application using the glib main loop (either directly or through libraries like GTK+ or Qt).
Being based on GLib, libgami allows development for multiple platform environments, in contrast to the .NET Technology-dependent AMIConnector. Its use of the C language makes it a more complex choice, providing the benefit of a unified development environment across multiple platforms.
This DLL is used on the progressive dialer QueueOCS something that can of great help when you need to see real source code examples and usage of the library.
