/ref> Two account types are currently available, and many of each type can be configured concurrently. Both types offer similar features including messaging, video and audio. The account types are SIP and Ring. A SIP account enables the Jami softphone to connect to a standard SIP server and a Ring account can register (or use an account set up) on the decentralised Jami network which requires no central server. By default, Jami uses a OpenDHT node maintained by Savoir-faire Linux to join the network when the user connects for the first time. However, the application gives users the choice to run this through their own bootstrap server in the advanced settings. By adopting

Design

Jami is based on a MVC model, with a daemon (the model) and client (the view) communicating. The daemon handles all the processing including communication layer (SIP/IAX), audio capture and playback, and so on. The client is a graphical user interface. D-Bus can act as the controller enabling communication between the client and the daemon.
