# Chat with other companies – *over an open standard*

XenRooms shares channels and direct messages with clients and partners over Matrix, the open standard for chat between servers – like Slack Connect, but with any company on XenRooms, Xenaxio or another Matrix server. Your administrator decides with whom.

## What you do with it

### Any Matrix server

Partners do not need XenRooms: Element, Synapse, Tuwunel and other Matrix servers talk to yours.

### The administrator decides

By default companies on Xenaxio and servers on the administrator’s list; all servers, or internal only, at a click.

### Clearly marked

Shared channels carry “External”, people from other companies “Other company” with their domain.

### Report and block

Invitations from outside are accepted only by choice; unwanted senders are reported and blocked.

## Questions

**Is XenRooms an alternative to Slack Connect?**

Yes. Shared channels and direct messages with other companies work over Matrix, an open standard: your partners can be on XenRooms, Xenaxio or any other Matrix server, not only on one vendor’s network.

**Do our partners need XenRooms?**

No. Any Matrix server works – for example Element with Synapse, or Tuwunel. If they have no chat yet, they can start XenRooms Free.

**Who decides which companies we chat with?**

The company’s administrator: internal only, companies on Xenaxio plus a list of servers (the default), or all Matrix servers.

**Where are messages of a shared channel stored?**

On your chat server and on the servers of the other companies in the channel – that is how Matrix works, like email. Their rules apply there.
