CAF: Working With Caf Call Legs
From TBwiki
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.
