To provide redundancy in the event the Succession Signaling Server fails,
install an additional Succession Signaling Server. A redundant Succession
Signaling Server also provides load-sharing for the TPS.
In a redundant configuration, one of the Succession Signaling Servers is
designated the Leader Succession Signaling Server. The second Succession
Signaling Server is designated as the Follower.
The Gatekeeper (Primary, Alternate, or Failsafe) must reside on the Leader
Succession Signaling Server. In the event of Leader Succession Signaling
Server failure, the Follower Succession Signaling Server assumes the role of
the Leader Succession Signaling Server.
