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…).

Linphone reviews

Love the features and concept. One of the few soft phones that triggers our music on hold from our sip pbx correctly. Some issues I noticed is that audio gets very distorted when other notifications are displayed on the Android phone. This is distracting as you can't hear the other party until the notification ends. There is an echo when setting up a conference call and you can't easily switch to other accounts if configured. Other than that, it works.

I have it set up with, following their configuration instructions. It works fine so long as the phone is awake. But when the screen goes to sleep, the app does not receive calls reliably. I have push notifications turned on, but they don't seem to work. If I activate the background mode to leave a permanent notification on the screen, it receives calls, but kills the battery quickly. Neither option is workable.

- Thomas Winger

No still has problem with Version 4.6.10. If I tap chat button at the bottom right, it freezes. On the Android version, If I tap Contact, it shows two chat icons, one with green shield and the other without. If I tap one without green shield, the app gets frozen. Why is this? Very annoying this needs to be fixed. Also chats do not seem to synchronize with Mobile app and PC desktop (Linux). Hope things will be improved.
