Linphone is an open-source communication app for making voice and video calls and sending instant messages over the internet. It is intended for personal use as well as workplaces that need a software phone compatible with SIP services. Because it uses the Session Initiation Protocol, Linphone can connect with compatible accounts and systems rather than relying on a single proprietary calling network.
Users can set up a SIP account and use Linphone to place and receive calls, hold video conversations, or exchange messages. Audio and video settings allow call quality to be adjusted to suit a device or connection, while codec options give more experienced users control over how media is encoded. Ringtones and interface themes can also be customized.
Privacy features include encrypted calls and messages, with support for SRTP and ZRTP. These protocols help protect communications in transit when supported by the account and the other party's software. Linphone's network settings provide additional configuration options for users working with particular services or adapting the app to a specific network environment.
The app can be used as a desktop softphone for everyday conversations, remote work, and calls through SIP-based business systems. Its open standards support interoperability with other compatible services and devices. Linphone's SDK also lets developers integrate its communication functions into their own applications, although that development use is separate from using the desktop client.
Linphone is available for Windows 10 and Windows 11, as well as other desktop and mobile platforms. Its open-source license makes it available without a purchase cost. To make calls through a SIP service, users need an account and suitable network access; the features available can depend on the service and the devices at the other end of a call.
