Cisco Webex Teams
Our partnerships with Slack, Microsoft, and Cisco means that we can offer you state-of-the-art chat application federation, without extra costs.
Syncing your favorite chat apps with Mio doesn't cost anything extra on top of your current costs for chat user accounts—even if you're using the free tiers.
