This parameter specifies the name that AuthBy DIAMETER uses to identify itself to a Diameter peer it connects to when no DiaPeerDef parameters are configured.

After the Diameter connection has been established, OriginHost sets the value of the Origin-Realm attribute in the Diameter messages sent to the peer. OriginHost is not optional and must be specified in the AuthBy DIAMETER clause. OriginHost defaults to the hostname of the server Radiator is running on. Special formatting characters are supported. Formatting is done when the configuration is loaded and AuthBy DIAMETER clause is activated.
