"Which cluster is used also depends on latency rather than just location. For example, a cloud cluster with lower STUN round-trip (SRT) delay than a Webex Video Mesh cluster may be a better candidate for the meeting. This logic prevents a user from landing on a geographically far cluster with a high SRT delay".
