  "abstract_en": "RFC 4458 (regarding SIP URIs for applications) defines a \"cause\" URI parameter, which may appear in the Request-URI of a SIP request, that is used to indicate a reason why the request arrived to the User Agent Server (UAS) receiving the message. This document updates RFC 4458 by creating a new predefined value for the \"cause\" URI parameter to cover service number translation for cases of retargeting due to specific service action leading to the translation of a called service access number. This document also provides guidance, which was missing in RFC 4458, for using the \"cause\" URI parameter within the History-Info header field, since this use is mandatory in some IP networks' implementations.",
