For the time being this is not on the roadmap, so I would suggest you ask a 3CX Partner to create a thread in the 'Ideas' section about this in the right category.Hi @VasilisV_3CX,
yes I know it's working on the old Windows client. I found this thread https://www.3cx.com/community/threads/auto-change-status-when-idle.63333/ where @StefanW wrote, that it's not implemented in the web client, because there is no reliable way to manage idleness from all browsers. But with the 3CX Desktop App you don't have multiple browsers to support. So it would be possible to implement that feature there.
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
