Designed for privacy

LISA is a fully self hosted, on-premises audio/video and chat communication service. It features web and mobile apps and is designed to offer the highest degree of security while being easy to use.

LISA lowers the barrier for communication and lets your team connect any time, any where, on any device, with each other, customers or partners.

LISA status indicators show when a message is sent and received - for more privacy, users can disable this on their side.

The optional LISA High Performance Backend enables enterprise class scalability, reliability and features.

Private, group and public calls

Talk makes it easy to call customers and partners in one-to-one or group-scenarios.

Users can invite external chat participants with an URL into public rooms on the Nextcloud server.

The chat, which remains open even when the user leaves a call, enables participants to easily exchange messages, links and notes.

Configurable visibility on chats allows team members and/or guests to find and join open chat rooms.
