Configuring PPP callback

PPP callback adopts the client/server model where the calling party is the callback client and the called party is the callback server. The client first originates a call, and the server decides whether to originate a return call. If a return call is needed, the callback server disconnects and then originates a return call according to the information such as username or callback number.

The following approaches are available to configure PPP callback with DCC:

• Configuring a PPP callback client in the C-DCC implementation

• Configuring PPP callback with RS-DCC
