17 * @mainpage Enhanced Call Control
18 *
19 * @section intro_sec Introduction
20 * This wraps and aggregates the SIPCC and CTI call control stacks, media stacks, and various additional
21 * components and glue necessary to start, configure and run them, and presents a high-level C++ API
22 * for connection, device selection and status, and call control.
23 *
24 * @section main_outline Outline
25 * @li The main entry point is CSF::CallControlManager, which is used to configure and start a
26 * call control stack.
27 * @li Configuration and events are raised to the CSF::ECC_Observer interface.
28 * @li Call Control is performed via CSF::CC_Device, CSF::CC_Line and CSF::CC_Call.
29 * @li Call Control events are raised to the CSF::CC_Observer interface.
30 * @li Audio/Video device selection and global media configuration is performed via CSF::AudioControl
31 * and CSF::VideoControl. Per-call media operations (mute, volume, etc) are integrated onto
32 * the CSF::CC_Call and CSF::CC_CallInfo interfaces.
