Can FLUX be set up to ring so I can choose to pick up or not?

FLUX connects in a direct way with other devices. There is no ring, but you can turn off auto connection, so you have to accept before someone can talk to you.


How can FLUX be muted?

There are 2 possibilities to mute:

    • close the app

If FLUX is not started but someone tries to talk to me, is there an automated notification for the sender?

There is no automated notification for the sender, but if FLUX app is not started or the WiFi connection is lost, your line on the screen of the devices turns grey and no one is able to talk to you. If you start FLUX app or if you get WiFi connection back, your line will turn blue again - which means that you are available.
