# Clusters

When a cluster is used, users may only access the cluster by using the repeater which is part of the cluster. The general talk group used is Talk Group ID 2. Further no outside access is enabled as the default configuration, meaning hotspot users will not be able to access it directly from a talk group ID.  Clusters also don't forward traffic to other master servers which means it only available at the master server it originates from.
