SFLphone design

SFLphone is based on a MVC model: Daemon and client are two separate processes that communicate through D-Bus. The Model is the daemon. Daemon handles all the processing including communication layer (SIP/IAX), audio capture and playback, etc. ... View is the GTK+ or KDE graphical user interface. Controller is D-Bus that enables communication between client and server.
