The PG router side A name object holds the host name of the
side A 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 B router is
the active router and a failure occurs, the side A router then
immediately assumes the role. In this case, the peripheral
gateway will lose its connection to the side B router and thus
use this object value to connect to the side A router.
