The PG router side B name object holds the host name of the
side B router that this enterprise contact center application
peripheral gateway functional component is associated. The
peripheral gateway component must be connected to a router
that is part of the same instance. If the side A router is
the active router and a failure occurs, the side B router then
immediately assumes the role. In this case, the peripheral
gateway will lose its connection to the side A router and thus
use this object value to connect to the side B router.
