# Microsoft Teams

## Overview

Microsoft Teams has no built-in ElevenAgents connector. How you make an ElevenLabs agent reachable in Teams depends on how users should reach it and what infrastructure you can run:

- a web widget embedded in a Teams tab,
- a phone number the agent answers (Azure Communication Services),
- a bot users call by name in Teams (Microsoft Graph media bot).

## Choosing an approach

::::card-grid
:::card{title="Widget tab" href="/guides/elevenagents-phone-numbers-microsoft-teams-widget-tab"}
Embed the ElevenLabs agent widget in a Teams tab. Click-to-talk in the Teams client. No telephony, no phone number.
:::

:::card{title="Phone number (ACS)" href="/guides/elevenagents-phone-numbers-microsoft-teams-azure-communication-services"}
Users dial a phone number that the agent answers, via Azure Communication Services Call Automation. PSTN, contact-center style.
:::

:::card{title="Calling bot (call by name)" href="/guides/elevenagents-phone-numbers-microsoft-teams-graph-media-bot"}
Call or chat with the agent by name in Teams, like a colleague — a Microsoft Graph media bot for voice plus Bot Framework messaging for text.

## At a glance

- **A fast internal demo or self-service assistant** — use the [widget tab](/guides/elevenagents-phone-numbers-microsoft-teams-widget-tab).
- **Customers calling a number that the agent answers (IVR / contact center)** — use [Azure Communication Services](/guides/elevenagents-phone-numbers-microsoft-teams-azure-communication-services).
- **Colleagues calling the agent by name inside Teams** — use the [Graph calling bot](/guides/elevenagents-phone-numbers-microsoft-teams-graph-media-bot).

:::callout{intent="note"}
Each approach has different access requirements — see the **Permissions & roles** section in each guide. In short: the widget needs Teams custom-app upload; ACS needs a paid subscription + Contributor; the calling bot needs an Azure Bot, Graph `Calls.AccessMedia.All`, and **admin consent** (Global Admin / Privileged Role Admin).
