Why Linhome?

Since many years, our company Belledonne Communications has been providing manufacturers, integrators, and developers of IP door entry solutions with high-quality client and server SIP-based software and advanced consultancy services.

Linhome for iOS, Linhome for Android, and the linhome.org website, have been developed to meet the emerging needs of intercom and video monitoring system developers to leverage a robust, secure and interoperable open source VoIP solution to build their own application.

What is Linhome?

The Linhome app is an open source client software designed to communicate via voice and video with door entry devices.
It is available for iOS and Android smartphones and tablets/iPads, and based on the same cross-platform library as Linphone. Thus, Linhome benefits from Linphone's long-term R&D work around the audio/video call quality.

Linhome is entirely based on standard telecom protocols (SIP, RTP) and is then interoperable with any SIP-compatible door entry station or server.

Main features:

• Early media video: see who is ringing before answering the call
• Two-way communication: communicate with visitors via voice and video with your mobile phone
• Call forking: decide where you want to pick up the call from, by registering several devices with the same SIP account
• Video surveillance: Configure the device you want to monitor and watch what's happening outside of your entrance
• Configurable action buttons: Set up remote actions, like unlocking a door or opening a gate (via DTMF or SIP INFO)
• Call history: Check out any missed call and automatically record visitors’ video
• Notifications: Be instantly notified of anyone ringing at your door, at any time and anywhere
• Easy configuration: Setup the app by entering your SIP credentials, flashing a Qr Code, or typing a remote provisioning URL
