This parameter specifies the name that <ServerDIAMETER> uses to identify itself to any connecting Diameter peers. It is sent to the peer in the Diameter CER message. It is not optional and must be specified in the <ServerDIAMETER> clause. Diameter peers may use OriginHost to determine whether they have connected to the correct peer, so it may be critical that it be configured correctly. Special formatting characters are supported.
