Teams need not only chats but calls: quick syncs within a department and meetings with external participants who would rather not install a separate app.

In “Matrix + Element” technology, group video and audio calls (Element Call) are built right into the messenger, and a guest can join by link without installation or an account.

  • Group video and audio calls are built into the corporate messenger.
  • A guest joins by link without installation and without an account.
  • Calls live in the same rooms where the work discussion happens.

Calls inside the messenger

Element Call provides group video and audio calls right from the work rooms. There is no need to switch to a separate service: the discussion, files, and the call are all in one space.

This is convenient for regular team meetings: the discussion context stays in the same room where the call took place, and it is easy to return to.

A guest by link without installation or an account

The main convenience for external meetings is guest calls by link. An external participant is sent a link and joins from the browser without installing an app or creating an account.

This removes the typical barrier to calls with contractors and partners who do not want to install a new client for a single meeting.

  • A guest joins by link straight from the browser.
  • No app installation required.
  • No separate account required for a one-off meeting.
  • An external participant sees only the relevant call, not the entire space.

Scenarios with external participants

Guest calls fit negotiations with contractors, consultations, interviews, and demos. The internal team works in its own space, and the external participant joins only the specific call.

Because the call is tied to a room, internal participants keep their work context while the guest gets access exactly to the meeting they were invited to.

How it fits into the corporate messenger

Calls are part of a single corporate messenger, not a separate product. The same roles, access rights, and rooms as in the chat define who starts a call and whom they can invite.

Deployment can be self-host or hosted, so the company chooses where the call infrastructure lives — on its own server or on the KMVSG side.

Quick checklist

  • Define the rooms that regularly need group calls.
  • Configure the rules for inviting external guests by link.
  • Test the guest sign-in scenario from the browser without installation.
  • Tie call access rights to roles in the messenger.
  • Choose the deployment model for the call infrastructure: self-host or hosted.

What to do next

KMVSG will implement group and guest video calls with Element Call as part of a Matrix + Element corporate messenger and tune them to your meeting scenarios.
