If you’re looking for more details about security for Slack’s call features, you’re in the right place!
Slack's voice and video calls use Opus and VP8 to encode audio and video respectively, and all traffic is encrypted in transit to protect the integrity and confidentiality of a call. Slack uses DTLS for the media stream and HTTPS for signaling with the media server.
Some metadata from a call is stored in Slack:
The name of a call
Where a call started in Slack (whether in a channel or direct message)
Who started and participated in a call
General performance metrics (latency, jitter, etc.)
The time a call starts and ends, and when members join or leave a call
Note: Logs or copies of calls are not recorded or stored in Slack. Slack's voice and video calls fall under the same security program as the rest of Slack. For more information, visit our Security policy.
Tip: If you have any questions about security or making calls in Slack, send us a note. We’d love to hear from you!
