Web browsers want to put tabs or applications that are not used for a long time to sleep. This all has to do with the importance of battery conservation. Our Webphone is not in charge of these functions. As a laptop user, you should therefore 'tell' your browsers and/or laptop yourself that you do not want that.
Is this already checked, but is the Webphone still not active? Then check the settings of your computer:
Check Prevent sleep/hibernation mode in the Webphone.WindowsMacOS
