VNC talk

Real-Time Office Communication Apps: chat, video and audio conferencing, broadcasts, screensharing wherever you are!

Business Communication with extensive features

VNCtalk is an unique enterprise real-time communication solution including chat, video and audio conferencing, screen sharing, voice messaging, file sharing, broadcasts, document collaboration and much more.

VNCtalk is available as a full featured Web Client in your browser, Desktop Client (Windows, Mac, Linux) and VNCtalk App (Android and iOS). Thus, VNCtalk is your comprehensive virtual communication tool on any device.

VNCtalk is entirely transparent and auditable on a code basis for our partners and customers. There is no security without open, transparent, readable, auditable code.

VNCtalk is available for on-premise installation and hosting in a datacenter of our partners' and customers' choice. This is the only way you can make sure your data are controlled by your trusted administrators and nobody else.

VNCtalk is widely customizable. Partners and customers can add their logo, CD/CI and at the same time modify the front end from a UX (user experience) perspective to add / remove modular functions. VNCtalk has users in various industries where we found very differing user stories.

VNCmeet, as part of VNCtalk, enables you to start video calls with external guest users. Guest users don’t need a VNCtalk subscription, a VNCtalk account and they don't need to download an App – just invite external participants with their email address and start a video meeting!

The VNCtalk App is a real alternative to WhatsApp or other SaaS based messengers. VNCtalk comes with the familiar features – and some more!

The VNCtalk App is of course free of advertising and it is equipped with the complete feature set such as chat/group chat, video/audio calls, screen share, file transfer, broadcasts and many more.

VNCtalk is seamlessly integrated into our VNClagoon stack. Start a chat or audio / video call – by simply clicking on a user avatar in VNCmail, VNCtask, VNCcontacts etc.

VNCtalk is equipped with state of the art backend technologies and products like PostgreSQL, Solr, Jitsi Meet, Prosody – all those tools are accessible via a powerful Restful API.

VNCtalk is scalable up to a huge number of users simultaneously on chats or video/audio calls. Due to the robust VNClagoon backend, it is possible to enhance bandwidth, add more instances and video bridges to auto scale up and scale down.

VNCtalk is our flagship product, so we have lots of ideas how to make it even more productive. Our product roadmaps are full of new and innovative features. And we are listening to our users, their needs and suggestions.
