1. 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 [RFC2119].

2. Introduction
The E.164 to Uniform Resource Identifiers (URI) Dynamic Delegation
Discovery System (DDDS) Application (ENUM) [RFC3761] transforms E.164
[E164] numbers into DNS names and the use of DNS services like
delegation through NS records, and use of NAPTR records in DNS.
Using this system, one can look up what services are available for a
specific domain name in a decentralized way with distributed
management of the different levels in the lookup process.
IAX [ID-IAX] is an "all in one" protocol for handling streaming media
in Internet Protocol (IP) networks. IAX combines both control and
media services in the same stream which decreases bandwidth usage and
improves Network Address Translation (NAT) transparency. These
design decisions have made IAX excel at handling Internet telephony.
The 'iax2:' URI scheme is also defined in the IAX protocol document.
This document registers the IAX2 Enumservice according to the
guidelines given in RFC3761 [RFC3761]. The IAX2 Enumservice is used
in provisioning the services field of a NAPTR resource record. This
field indicates what class of functionality a given end point offers.
The registration is defined within the DDDS (Dynamic Delegation
Discovery System [RFC3401] [RFC3402] [RFC3403] [RFC3404] ) hierarchy,
for use with the "E2U" DDDS Application defined in RFC3761.

3. IAX2 Service Registration
Enumservice Name: "IAX2"
Enumservice Type: "iax"
Enumservice Subtype: iax2
URI Scheme: "iax2:"
Functional Specification:
The IAX2 Enumservice indicates that the resource identified by the
associated URI scheme is capable of being contacted using the IAX2
protocol to provide a communication session.
A client selecting this NAPTR will have support for originating a
call utilizing the IAX2 protocol [ID-IAX].
Security Considerations:
There are no specific security issues with this Enumservice.
However, the general considerations of Section 6 apply.
Intended Usage: COMMON

4. Examples
4.1. Simple IAX Registration
The following is an example of the use of the enumservice registered
by this document in a NAPTR resource record.
$ORIGIN 8.4.1.0.6.4.9.7.0.2.4.4.e164.arpa.
@ IN NAPTR 10 100 "u" "E2U+iax:iax2" "!^.*$!iax2:example.com/
charlie!"
This contact information indicates that the domain
8.4.1.0.6.4.9.7.0.2.4.4.e164.arpa. may be contacted by using the IAX2
protocol at domain 'example.com' with the identifier 'charlie'.
4.2. Registration with Preference Order
The next example demonstrates that the domain
3.8.0.0.6.9.2.3.6.1.4.4.e164.arpa. is preferably contacted by IAX2,
secondly via SIP, and then H.323 for voice, and lastly by SMTP for
messaging. Note that the tokens "iax", "sip", "h323", and "msg" are
Types registered (or to be registered) with IANA, and they have no
implicit connection with the protocols or URI schemes with the same
names.
In each case, the next step in the resolution process is to use the
resolution mechanism appropriate to each of the protocols, (specified
by the URI schemes iax, sip, h323 and mailto).
$ORIGIN 3.8.0.0.6.9.2.3.6.1.4.4.e164.arpa.
@ IN NAPTR 10 100 "u" "E2U+iax" "!^.*$!iax2:example.com/mccarthy!" .
@ IN NAPTR 10 101 "u" "E2U+sip" "!^.*$!sip:mccarthy@example.com!" .
@ IN NAPTR 10 101 "u" "E2U+h323" "!^.*$!h323:mccarthy@example.com!" .
@ IN NAPTR 10 102 "u" "E2U+msg" "!^.*$!mailto:mccarthy@example.com!"
.

5. Registration with an IAX context
The following is an example of the use of the enumservice registered
by this document in a NAPTR resource record that contains a
destination 'context'.
$ORIGIN 9.4.1.0.6.4.9.7.0.2.4.4.e164.arpa.
@ IN NAPTR 10 100 "u" "E2U+iax:iax2" "!^.*$!iax2:example.com/
joe?developers!"
This contact information indicates that the domain
9.4.1.0.6.4.9.7.0.2.4.4.e164.arpa. may be contacted by using the IAX2
protocol at domain 'example.com' with the identifier 'joe' in the
context (or user partition) 'developers'.

6. Security Considerations
The IAX Enumservice does not introduce any new security issues beyond
any already present in the DNS and IAX protocols except that this
Enumservice provides another fact that may be harvested and possibly
exploited.
The use of DNSSEC [RFC2535] is recommended to improve operational
security.

7. IANA Considerations
This document requests registration of the "iax" Enumservice with the
'iax2' sub-type according to the guidelines and specifications in RFC
3761 [RFC3761] and the definitions in this document.
