      # @option options [String] :subaccount auth_id of the subaccount. Lists only those recordings of the main accounts which are tied to the specified subaccount.
      # @option options [String] :call_uuid Used to filter recordings for a specific call.
      # @option options [String] :add_time Used to filter out recordings according to the time they were added.The add_time filter is a comparative filter that can be used in the following four forms:
      #                                    - add_time\__gt: gt stands for greater than. The format expected is YYYY-MM-DD HH:MM[:ss[.uuuuuu]]. Eg:- To get all recordings that started after 2012-03-21 11:47, use add_time\__gt=2012-03-21 11:47
      #                                    - add_time\__gte: gte stands for greater than or equal. The format expected is YYYY-MM-DD HH:MM[:ss[.uuuuuu]]. Eg:- To get all recordings that started after or exactly at 2012-03-21 11:47[:30], use add_time\__gte=2012-03-21 11:47[:30]
      #                                    - add_time\__lt: lt stands for lesser than. The format expected is YYYY-MM-DD HH:MM[:ss[.uuuuuu]]. Eg:- To get all recordings that started before 2012-03-21 11:47, use add_time\__lt=2012-03-21 11:47
      #                                    - add_time\__gte: lte stands for lesser than or equal. The format expected is YYYY-MM-DD HH:MM[:ss[.uuuuuu]]. Eg:- To get all recordings that started before or exactly at 2012-03-21 11:47[:30], use add_time\__lte=2012-03-21 11:47[:30]
      #                                    - Note: The above filters can be combined to get recordings that started in a particular time range.
      # @option options [Int] :limit Used to display the number of results per page. The maximum number of results that can be fetched is 20.
      # @option options [Int] :offset Denotes the number of value items by which the results should be offset. Eg:- If the result contains a 1000 values and limit is set to 10 and offset is set to 705, then values 706 through 715 are displayed in the results. This parameter is also used for pagination of the results.
