What’s New in Microsoft Teams - Juni 2025
Microsoft continues to enhance the Teams Phone experience with powerful updates that boost productivity, accessibility, and call quality. Here’s a roundup of the latest features released in June 2025 for Teams Phone users, admins, and device managers.
Copilot Now Supports Transferred Calls
AI is taking over the transfer process — in a good way. With Copilot summaries for transferred calls, users can now:
- Automatically generate a call summary
- Edit it as needed
- Send it to the transfer target
This reduces the need for consultative transfers and ensures context is never lost, leading to faster and smoother handoffs.
Available on desktop and Teams Phone devices
