Walkie Talkie app in Microsoft Teams

The Walkie Talkie app in Teams provides instant push-to-talk (PTT) communication for your team and is now available on Android. Walkie Talkie allows users to connect with their team using the same underlying channels they're members of. Only users who connect to Walkie Talkie in a channel become participants and can communicate with each other using push-to-talk, one at a time.

With Walkie Talkie in Teams, firstline workers can now securely communicate with a familiar PTT experience without needing to carry bulky radios, and Walkie Talkie works anywhere with WiFi or cellular internet connectivity.

Getting started

Deploying Walkie Talkie

Currently, Walkie Talkie is not pre-installed. To enable this feature for users in your organization, you need to add Walkie Talkie to the App Setup Policy assigned to users from the Teams Admin Center.

Once enabled, Walkie Talkie will become available on the Android app within 48 hours.

Adding Walkie Talkie to your app list

In the Microsoft Teams admin center, under Teams app > Setup policies, you should have Allow user pinning set to On. Then, under the Pinned Apps section, click +Add Apps.

Shows the Pinned apps section and the Add Apps button to be selected.

On the Add pinned apps panel that appears on the right, use the Search textbox to look for Walkie Talkie. When you have it as a search result, click the Add button to the right of the name to add it to your list.

Shows the Add pinned apps sidebar with Walkie entered into the search pane and the Walkie Talkie app in the search results, with the Add button next to it.

The Walkie Talkie app should now appear on the Pinned Apps list, and be available for use once you click the Save button.

Shows the Pinned apps list with the Walkie Talkie app added, and the Save button underneath the list.

Network documentation

Walkie Talkie in Teams requires Internet connectivity and below the network conditions are required for optimal experience.

Metric Required
Latency (RTT) < 300ms
Jitter < 30ms
Packet Loss < 1%

As noted above, the quality of real-time media over an IP network is greatly impacted by the quality of the network connectivity, but especially by the amount of:

  • Latency - This is the time it takes to get an IP packet from point A to point B on the network. This network propagation delay is essentially tied to physical distance between the two points and the speed of light, including additional overhead taken by the various routers in between. Latency is measured as Round-trip Time (RTT).
  • Packet Loss - This is often defined as a percentage of packets that are lost in a given window of time. Packet loss directly affects audio quality—from small, individual lost packets having almost no impact, to back-to-back burst losses that cause complete audio cut-out.
  • Jitter - This is the average change in delay between successive packets.

Expected data usage from Walkie Talkie is around 20KB/s when sending or receiving audio. When idle, expected data usage from Walkie Talkie is negligible.

Walkie Talkie devices

FirstLine workers often need to speak and receive Walkie Talkie calls even when their phones are locked. This experience is possible through specialized devices with a dedicated PTT button.

Note

These devices are not Teams certified. They have been validated to work with Teams Walkie Talkie.

License requirements

Walkie Talkie app is included in all paid licenses of Teams in Office 365 subscriptions. For more information about getting Teams, check out How do I get access to Microsoft Teams?

Note

Certain advanced features may require additional licensing. For example, integration with Samsung Galaxy XCover Pro requires a Knox license.

Further information

  • ITAdmins can maintain control over who is using Walkie Talkie through App Policies.
  • If your firstline worker is using mobile data to communicate via Teams, Walkie Talkie will use the same method.
  • Walkie Talkie should work well in low bandwidth situations, or situations where your smartphone is connected and working. Walkie Talkie will not work when there is no connectivity at all.
