This string defines the Diameter realm that is used as
Destination-Realm for SWx messages. If HSSRealm is
not defined, DiaPeerDef entries need to be configured
and DestinationRealm from Diameter Peer's DiaPeerDef configuration is used
as the Destination-Realm. If no HSSRealm or
Destination-Realm for the chosen DiaPeerDef is configured,
Destination-Realm in the outgoing SWx request is empty.
Starting
with Radiator 4.24, the recommended configuration is to define
HSSRealm and leave DiaPeerDef
parameters undefined. This allows Radiator to use Diameter routing to
resolve the peer to send SWx requests to.
# Always use this as SWx Destination-Realm in requests
