Updated December 3, 2025: We have updated the timeline. Thank you for your patience. 

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.
