About Linphone
Linphone is an internet phone app built on SIP, the open standard used by office phone systems and VoIP providers around the world. The project dates back to 2001 and is developed today by Belledonne Communications, a French company. Instead of tying you to one network, Linphone works with any SIP account: your company's phone system, a VoIP provider, or a free linphone.org address you can create inside the app.
You can place clear audio and HD video calls, send instant messages with photos and files, run group chats, and hold audio or video conferences. Messages and conferences can be end-to-end encrypted, and calls are protected with SRTP and ZRTP. Push notifications let Linphone ring for incoming calls without having to run constantly in the background.
Linphone is free, has no ads and is open source under the GPL-3.0 licence.
