A VoIP network\r\nelement may receive a URI containing an E.164 number, where that URI\r\ncontains an \"enumdi\" parameter.  The presence of the \"enumdi\"\r\nparameter indicates that an ENUM query has already been performed on\r\nthe E.164 number by a previous VoIP network element.  Equally, if a\r\nVoIP network element sends such a URI, it asserts that an ENUM query\r\nhas been carried out on this number.
