Linphone features a streamlined user interface that promotes the easy discovery of all its tools, starting with a prominently placed home dashboard screen with easy to find Contacts listing. The configuration window of this app is quite important because there users can set up their display name and manage login credentials, set their bandwidth limitations and networking options, configure audio parameters (recording, playback, and ringer devices), check if their webcam is properly detected, set active video codec, add security measures (including one of the offered encryption sets – SRTP, ZRTP, and DTLS), and more.

Advanced users can take full advantage of this VoIP platform by integrating parts of it into their own projects via included API and cross-platform SDK platform.
