Microsoft Ignite 2025 introduced a series of impactful updates to Teams Phone. These improvements strengthen enterprise calling, enhance mobile usability, and expand compliance capabilities.

Microsoft 365 Copilot in the Calls App

Teams Phone now integrates Microsoft 365 Copilot Chat directly into the Calls app, on both desktop and mobile.

Copilot now delivers:

Smart post-call summaries
Key insights from the conversation
Suggested follow-up actions
Contextual intelligence using Microsoft Graph and web data

This significantly boosts productivity for users who rely heavily on calling workflows.

Shared Call Line Pickup Indicators (Mobile)

Delegates can now:

Resume held calls from shared lines directly on Teams Mobile
See “answered by” and “resumed by” labels
Collaborate more effectively during busy call flows

This brings important parity between desktop and mobile call-handling.

Set Teams Mobile as Default Calling App (iPhone)

iPhone users can now set Teams Mobile as the system-wide default dialer.

Benefits include:

All calls originating from Contacts or Call History route through Teams
Better compliance and call recording alignment
A fully unified business calling experience

Compliance Recording for Call Queues

Teams now supports third-party ISV compliance recording at the call queue level.

This enables:

Policy-based recording
Better coverage for dynamic queue memberships
Seamless integration with existing compliance ecosystems

Ideal for organisations in regulated industries.

Microsoft Teams Phone continues evolving into a truly enterprise-grade telephony platform with strong AI capabilities and compliance-focused enhancements.
