Walkie Talkie app in Microsoft Teams
This is a preview or early release feature.
The Walkie Talkie app in Teams provides instant push-to-talk (PTT) communication for your team and is available in Public Preview 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.
Deploying Walkie Talkie
During the Public Preview, 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.
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.
The Walkie Talkie app should now appear on the Pinned Apps list, and be available for use once you click the Save button.
Walkie Talkie in Teams requires Internet connectivity and below the network conditions are required for optimal experience.
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.
- Rugged phones
These devices are not Teams certified. They have been validated to work with Teams Walkie Talkie.
Certain advanced features may require additional licensing. For example, integration with Samsung Galaxy XCover Pro requires a Knox license.
- 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.
