 OPTIONAL PARAMETERS
 -------------------
+abort-conference-count
+    Only has an effect if the prometheus exporter is enabled and if it is not
+    empty (default).
+    If at least this many conferences are active on the server, the type will
+    bail out before making any changes.
+    This is useful if you want to avoid service disruptions due to e.g. an SLA.
+
+
 turn-secret
     The shared secret for the TURN server.
