RFC 6118 Update Legacy Enumservice Registrations March 2011
1. Introduction
[RFC6117] has obsoleted the IANA registration section of [RFC3761].
Since the IANA Enumservice registry contains various Enumservices
registered under the regime of RFC 3761, those registrations do not
conform to the new guidelines as specified in [RFC6117]. To ensure
consistency among all Enumservice registrations at IANA, this
document adds the (nowadays) missing elements to those legacy
registrations. Furthermore, all legacy Enumservice registrations are
converted to the new XML-chunk format, and, where deemed necessary,
minor editorial corrections are applied.
However, this document only adds the missing elements to the XML
chunks as specified in the IANA Considerations section of [RFC6117],
but it does not complete the (nowadays) missing sections of the
corresponding Enumservice Specifications. In order to conform with
the new registration regime as specified in [RFC6117], those
Enumservice Specifications still have to be revised.
It is important to note that this document does not update the
functional specification of the concerned Enumservices.
The following RFCs are updated by this document:
o [RFC3762]
o [RFC3764]
o [RFC3953]
o [RFC4143]
o [RFC4002]
o [RFC4238]
o [RFC4355]
o [RFC4415]
o [RFC4769]
o [RFC4969]
o [RFC4979]
o [RFC5028]
o [RFC5278]
o [RFC5333]
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119 [RFC2119].
Hoeneisen & Mayrhofer Standards Track [Page 4]
RFC 6118 Update Legacy Enumservice Registrations March 2011
3. IESG Action
According to [RFC3761], any Enumservice registration had to be
published as a Standards Track, Experimental, or BCP (Best Current
Practice) RFC. [RFC6117] no longer has this requirement, i.e.,
"Specification Required", which implies the use of a Designated
Expert [RFC5226], is sufficient.
This document changes the approval requirement for updates to
Enumservice registrations to Specification Required, whereby the
specification and request are reviewed by a Designated Expert as
described in [RFC6117].
4. Legacy Enumservice Registrations Converted to XML Chunks
In the following, the legacy Enumservice Registrations are converted
to XML chunks that include the new elements introduced by [RFC6117].
(Note that references in Sections 4.1 - 4.39 refer to the references
section within the respective Enumservice Specification.)

Within and between MMS Environments (MMSE,
network infrastructures that support the MultiMedia
Service), other pieces of state data (for example,
charging-significant information) are exchanged
between MMS Relay Servers. Thus, although these
servers use SMTP as the "bearer" for their
application exchanges, they map their internal state
to specialized header fields carried in the SMTP message
exchanges. The header fields used in such MMSE are
described in detail in [17].

<additionalinfo>
<paragraph>
The MMS Architecture describes an interface
between the MMSE and "legacy messaging systems"
(labelled as MM3) that accepts "standard" SMTP
messages. Thus, although the MMS Relay Server that
supports this interface appears as a standard SMTP
server from the perspective of an Internet-based
mail server, it acts as a gateway and translator,
adding the internal state data that is used within
and between the MMS Environments. This mechanism is
described in [17], which also includes references to
the specifications agreed by those bodies
responsible for the design of the MMS.

Note that MMS can be used as an alternative to
deliver an SMS RP-DATA RPDU if, for example, the
SMS bearer is not supported. If an entry includes
this Enumservice, then in effect this can be taken
as implying that the recipient is capable of
receiving EMS or SMS messages at this address. Such
choices on the end system design do have two small
caveats; whilst in practice all terminals supporting
MMS today support SMS as well, it might not
necessarily be the case in the future, and there may

be tariff differences in using the MMS rather than
using the SMS or EMS.

</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
Hoeneisen & Mayrhofer Standards Track [Page 34]
RFC 6118 Update Legacy Enumservice Registrations March 2011
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.

This Enumservice indicates that the resource identified by
the associated URI scheme is capable of being a source of
information, which can be contacted using TLS or the Secure
Socket Layer protocol.
</paragraph>
<paragraph>
Note that the kind of information retrieved can be manifold.
Usually, contacting a resource by an 'https:' [12] URI
provides a document. This document can contain references
that will trigger the download of many different kinds of
information, such as text, audio, video, executable code, or
even voice message files. Thus, one cannot be more specific
about the kind of information expected when contacting the
resource.

Enumservice Subtype: "tel"
URI Scheme: 'tel:'
Functional Specification:
This Enumservice indicates that the resource identified by the
associated URI scheme is capable of receiving a message using
the Multimedia Messaging Service (MMS) [15].
For references see [RFC4355]
Security Considerations:
There are no specific security issues with this Enumservice.
However, the general considerations of Section 6 of [RFC4355]
apply.
Intended Usage: COMMON
Authors:
Rudolf Brandner, Lawrence Conroy, Richard Stastny (for author
contact detail see [RFC4355])
Any other information the author deems interesting:
Note that MMS can be used as an alternative to deliver an SMS
RP-DATA RPDU if, for example, the SMS bearer is not supported.
If an entry includes this Enumservice, then in effect this can
be taken as implying that the recipient is capable of receiving
EMS or SMS messages at this address. Such choices on the end
system design do have two small caveats; whilst in practice all
terminals supporting MMS today support SMS as well, it might
not necessarily be the case in the future, and there may be
tariff differences in using the MMS rather than using the SMS
or EMS.

Within and between MMS Environments (MMSE, network
infrastructures that support the MultiMedia Service), other
pieces of state data (for example, charging-significant
information) are exchanged between MMS Relay Servers. Thus,
although these servers use SMTP as the "bearer" for their
application exchanges, they map their internal state to
specialised headers carried in the SMTP message exchanges.
The headers used in such MMSE are described in detail in [17].
For references see [RFC4355]

RFC 6118 Update Legacy Enumservice Registrations March 2011
Security Considerations:
There are no specific security issues with this Enumservice.
However, the general considerations of Section 6 of [RFC4355]
apply.
Intended Usage: COMMON
Authors:
Rudolf Brandner, Lawrence Conroy, Richard Stastny (for author
contact detail see [RFC4355])
Any other information the author deems interesting:
The MMS Architecture describes an interface between the MMSE and
"legacy messaging systems" (labelled as MM3) which accepts
"standard" SMTP messages. Thus although the MMS Relay Server
that supports this interface appears as a standard SMTP server
from the perspective of an Internet-based mail server, it acts
as a gateway and translator, adding the internal state data that
is used within and between the MMS Environments. This mechanism
is described in [17], which also includes references to the
specifications agreed by those bodies responsible for the design
of the MMS.
Service Name: E.164 to VPIM MailTo: URL
URI Type: "Mailto:"
Type: VPIM
Subtype: MAILTO
Functional Specification: See section 4.2 through 4.4 of [RFC4238]
Intended Usage: COMMON
Author: Greg Vaudreuil (gregv&ieee.org)
Error Conditions:
o E.164 number not in the numbering plan
o E.164 number in the numbering plan, but no URLs exist for that
number
o E2U+VPIM:Mailto Service unavailable
Security Considerations:
o Malicious Redirection
One of the fundamental dangers related to any service such as
this is that a malicious entry in a resolver's database will
cause clients to resolve the E.164 into the wrong email URL.
The possible intent may be to cause the client to send the
information to an incorrect destination.
o Denial of Service
By removing the URL to which the E.164 maps, a malicious
intruder may remove the client's ability to access the
resource.
o Unsolicited Bulk Email
The exposure of email addresses through the ENUM
service provides a bulk mailer access to large numbers
of email addresses where only the telephone number was
previously known.

Service Name: E.164 to VPIM LDAP URL
URI Type: "LDAP:"
Type: VPIM
Subtype: LDAP
Functional Specification: See section 3.2 through 3.3 of [RFC4238]
Intended Usage: COMMON
Author: Greg Vaudreuil (gregv&ieee.org)
Security Considerations:
o Malicious Redirection
One of the fundamental dangers related to any service
such as this is that a malicious entry in a resolver's
database will cause clients to resolve the E.164 into
the wrong LDAP URL. The possible intent may be to cause
the client to connect to a rogue LDAP server and
retrieve (or fail to retrieve) a resource containing
fraudulent or damaging information.
o Denial of Service
By removing the URL to which the E.164 maps, a
malicious intruder may remove the client's ability to
access the LDAP directory server.
Enumservice Name: "voice"
Enumservice Type: "voice"
Enumservice Subtype: "tel"
URI Scheme: 'tel:'
Functional Specification:
The kind of communication indicated by this Enumservice is
"Interactive Voice". From a protocol perspective, this
communication is expected to involve bidirectional media streams
carrying audio data.
A client may imply that the person controlling population of a
NAPTR holding this Enumservice indicates their capability to
engage in an interactive voice session when contacted using the
URI generated by this NAPTR.
Security Considerations:
See Section 5 of [RFC4415]
Intended Usage: COMMON
Authors: Rudolf Brandner, Lawrence Conroy, Richard Stastny (for
author contact detail see Authors' Addresses section)
Any other information the author deems interesting:
o 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.
o The kind of subsystem required to initiate a Voice Enumservice
with this sub-type is a "Dialler". This is a subsystem that
either provides a local connection to the PSTN or PLMN, or that
provides an indirect connection to those networks. The
Hoeneisen & Mayrhofer Standards Track [Page 57]
RFC 6118 Update Legacy Enumservice Registrations March 2011
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.
o 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.
o The "tel:" URI value SHOULD be fully qualified (using the
"global phone number" form of RFC3966 [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.
Enumservice Name: "pstn"
Enumservice Type: "pstn"

Functional Specification:
This Enumservice indicates that the resource identified
is an 'im:' URI. The 'im:' URI scheme does not identify
any particular protocol that will be used to handle
instant messaging receipt or delivery, rather the mechanism
in RFC 3861 [4] is used to discover whether an IM protocol
supported by the party querying ENUM is also supported by
the target resource.
