IP Phone registration on a CS 1000 system
On a CS 1000 system, the IP Phones register with the LTPS on the Signaling
Server. If a secondary Signaling Server exists, the IP Phone registrations are
split between the primary and secondary Signaling Servers to aid in load
balancing. In that case, the IP Phone registrations alternate between the
primary and secondary Signaling Servers.
