 Call diagnostics logs provide important information about the endpoints and the media transfers for each participant. They also provide measurements that help you understand quality problems.
 
-For each endpoint within a call, a distinct call diagnostics log is created for outbound media streams (audio or video, for example) between endpoints. In a P2P call, each log contains data that relates to each of the outbound streams associated with each endpoint. In group calls, `participantId` serves as a key identifier to join the related outbound logs into a distinct participant connection. Call diagnostics logs remain intact and are the same regardless of the participant tenant.
