MC1183611 - Consult and merge into a meeting or group call via Dual-Tone Multi-Frequency (DTMF)

Introduction

To improve collaboration and streamline meeting workflows, Microsoft Teams is introducing the ability to consult and merge Public Switched Telephone Network (PSTN) callers into active meetings—even when those callers are behind auto-attendants or Interactive Voice Response (IVR) systems that require Dual-Tone Multi-Frequency (DTMF) navigation. This enhancement allows users to reach subject matter experts via dial-in and seamlessly bring them into the broader conversation.

This message is associated with Microsoft 365 Roadmap ID 518218.

• Targeted Release: Rolling out early January 2026, expected to complete by mid-January 2026.
