Discord's developer documentation says that voice data is carried over UDP in both directions, so a client that joins a voice channel must be able to receive UDP packets.

Open the original- What it measures
- The page is written for developers who build bots and clients. It describes the protocol that any client uses to join a voice channel, not a feature of the Discord app.
- What it does not show
- The documentation describes what a client can receive. It does not say whether Discord or any third party records or transcribes that audio, and recording a call still needs the consent of the people in it.
