Known Issues

Intercom

There may be issues with the intercom functionality if the page is reloaded by anybody after the director view has been loaded. In order to re-connect all intercom connections, do the following:

1. Refresh all non-director views with talkback enabled
2. Refresh the director view

To avoid problems, make sure that no devices have an automatic screen turn-off or lock enabled; this is especially an issue on some smartphones.

A possible suggestion to fix this is to move the mute/listening states into a session-long database, so state is saved on the server, and on reconnect of each client (director or other), the mute/unmute states are re-established from what is saved in the database.

iOS

Intercom & Fullscreen mode not fully supported on iOS. This is a limitation by Apple and cannot be solved with a web-app.

Compatibility

We recommend to use Chrome for the director and the camera clients. Firefox currently shows issues with the intercom, this is due to an issue with peerJS and should be fixable. We do not recommend the use of Safari. Microsoft EDGE and the latest version of Internet Explorer should be working, but this has not been tested.

Others

• Scheduling has not been implemented
