Linphone is a free program that allows users to make voice and video calls, as well as send and receive text messages. If you have a WiFi, 3G, or 4G internet connection, Linphone makes it possible for you to be reachable at all times, even while the app itself is closed.
The following are some of the important features of Linphone: * audio and video calls in high quality * audio conference calls with several participants * the ability to share photographs and files * Linphone accounts that can be accessed at any time, even if the app is closed (thanks to push notifications)
* compliant with a wide number of SIP-compatible VoIP service providers * secure communication (options for encryption) * allows for the ability to communicate with anyone who possesses a “traditional” phone line
Linphone is compatible with the most popular mobile and desktop operating systems, and it provides a wide variety of specialized capabilities for users with more experience (codecs, transport standard, encryption options, DTMF…).
