CAF: Working With Caf Call Legs

Overview

CAF Call leg (CTBCAFCallLeg):

The CTBCAFCallLeg class is a wrapper around the CTBCMCLeg object. It's enhancing the CTBCMCLeg object so multiple call legs can be grouped and managed together from a parent Call object (CTBCAFCallFlow).

CAF Call Flow (CTBCAFCallFlow):

The CTBCAFCallFlow base class contains one or multiple CTBCAFCallLeg objects. The role of the CTBCAFCallFlow object is to implement a call flow that involves actions on legs that have a relation with each other.

CAF Call Bridge (CTBCAFBridge, based on CTBCAFCallFlow):

A typical implementation of a call flow is the CTBCAFBridge class (based on the CTBCAFCallFlow base class). This class is designed to - Receive an incoming call - Make a corresponding outgoing call - Join them together - Terminate both of them when one leg hangups.

CAF Call Behavior (CTBCAFCallBehavior):

Behaviors CTBCAFCallBehavior can be attached to a call flow (CTBCAFCallFlow). Their role is to modify the basic call flow, decorating it with optional functionality (CDR logging, FAX detection, Ring tone playback, etc.)
