          Specifies the maximum number of QI values which can be reported for a
          session. If this parameter is empty there is no specified maximum
          limit.

          If possible this limit SHOULD be large enough to handle at least 10
          to 15 minutes of call time, which would typically mean 60 to 90
          quality values for commonly used quality models.

      <description>
        SIP client table (a Client as described in {{bibref|TR-104i2|Section
        4.2}}). Each SIP client maintains its identity-to-location (i.e.,
        RegisterURI-to-ContactURI) binding for SIP signaling exchanged between
        the client and the network.

        For CPE use cases where {{object|.CallControl}} is used to map
        network-facing to user-facing objects, the relationship between the SIP
        client object and its associated {{object|.CallControl.Line}} object(s)
        is determined by the {{param|RegisterMode}} parameter, as follows:

        : - In case of RFC3261-style explicit registration of SIP AoRs, only a
          single line shall be associated with each SIP client.

        : - In case of RFC6140 or IMS/TISPAN-style registration, multiple lines
          can be associated with each SIP client. The set of lines associated
          with a SIP client constitute an 'identity set'. In this case,
          registering the single SIP client implicitly registers the identities
          of all associated lines.

        : - In the case where the client does not register with the network
          ({{param|RegisterMode}} is {{enum|STATIC|RegisterMode}}), multiple
          lines can be associated with each SIP client.

        The {{object}} is a table that is used to control which extensions ring
        when an incoming call is received.

        The map approach separates the call routing aspects from the
        configuration of the lines and extensions. It support PBX concepts such
        as DDI (one extension per line) and groups (parallel dialing if
        extensions have same priority and hunting when extensions have
        different priority).

          model used is specified by {{param|.VoIPProfile.{i}.QIModelUsed}}.

          The statistics values in this list MUST be in time order, with the
          oldest one first and the most recent one last.

          For long sessions the number of values might exceed the limit given
          by {{param|.Capabilities.QualityIndicator.MaxQIValues}}. In that
          case, the CPE MUST remove the oldest values to keep the number of
          reported values within the limit.

          The interpretation of the QI values are algorithm-specific, the only
          constraints being the range and the fact that lower values indicate
          worse quality than do higher values.

          For instance, if {{param}} is reported as "78,57,88,79,34,56", and
          {{param|.VoIPProfile.{i}.QICalculationInterval}} is 10 seconds, the
          quality during the first ten seconds was 78, the next ten seconds 57,
          and so on. The last reported value (here 56) might cover a shorter
          time period than {{param|.VoIPProfile.{i}.QICalculationInterval}},
          but the length can be deduced using {{param|##.Duration}}.

          model used is specified by {{param|.VoIPProfile.{i}.QIModelUsed}}.

          The statistics values in this list MUST be in time order, with the
          oldest one first and the most recent one last.

          For long sessions the number of values might exceed the limit given
          by {{param|.Capabilities.QualityIndicator.MaxQIValues}}. In that
          case, the CPE MUST remove the oldest values to keep the number of
          reported values within the limit.

          The interpretation of the QI values are algorithm-specific, the only
          constraints being the numeric range and the fact that lower values
          indicate worse quality than do higher values.

          For instance, if {{param}} is reported as "78,57,88,79,34,56", and
          {{param|.VoIPProfile.{i}.QICalculationInterval}} is 10 seconds, the
          quality during the first ten seconds was 78, the next ten seconds 57,
          and so on. The last reported value (here 56) might cover a shorter
          time period than {{param|.VoIPProfile.{i}.QICalculationInterval}},
          but the length can be deduced using {{param|##.Duration}}.
