        <paragraph>
          This Enumservice indicates that the person
          responsible for the NAPTR is accessible via the PSTN
          (Public Switched Telephone Network) or PLMN (Public
          Land Mobile Network) using the value of the
          generated URI.
        </paragraph>
        <paragraph>The kind of subsystem required to initiate a
          Voice Enumservice with this Subtype is a "Dialler".
          This is a subsystem that either provides a local

Top      Up      ToC       Page 35 
          connection to the PSTN or PLMN, or that provides an
          indirect connection to those networks.  The
          subsystem will use the telephone number held in the
          generated URI to place a voice call.  The voice call
          is placed to a network that uses E.164 numbers to
          route calls to an appropriate destination.
        </paragraph>
        <paragraph>
          Note that the PSTN/PLMN connection may be
          indirect.  The end user receiving this NAPTR may
          have a relationship with a Communications Service
          Provider that accepts call initiation requests from
          that subsystem using an IP-based protocol such as
          SIP or H.323, and places the call to the PSTN using
          a remote gateway service.  In this case, the Provider
          may either accept requests using "tel:" URIs or has
          a defined mechanism to convert "tel:" URI values
          into a "protocol-native" form.
        </paragraph>
        <paragraph>
          The "tel:" URI value SHOULD be fully qualified
          (using the "global phone number" form of RFC 3966
          [10]).  A "local phone number" as defined in that
          document SHOULD NOT be used unless the controller of
          the zone in which the NAPTR appears is sure that it
          can be distinguished unambiguously by all clients
          that can access the resource record and that a call
          from their network access points can be routed to
          that destination.
