the tipping point
countries A-Z
 retail services
going IP (40%
French phones
work over IP)
 growing
number of
services going
all IP
service pressure
to move to IP
until now:
 international
wholesale bilaterals
were mostly in TDM
(IP limited to
hubbing)
today:
countries A-Z
 new IP based
business
models appear
(flat retail
rates)
 TDM is full
 Main international
operators will migrate
bilaterals (over 70%
of international
traffic) over IP in 2009
network, peer and
service pressure to
move to IP
 new voice

the IP transition: what is at stake today
maintaining & enhancing the customer
experience
scale
quality
security
interoperability
strengthening the pillars of our business in a new
environment
what is the i3 forum
eight major carriers team-up in Q3 2007



AT&T, Deutsche Telekom, Orange, SingTel, Telecom Italia Sparkle, Telefónica, TPSA, TeliaSonera
1 billion fixed and mobile customers in over 80 countries, approximately 40% of Int’l Voice traffic
14 more carriers join in 2H08 : Tata, Telus, Rogers, Sprint, BT, BICS, Telkom Austria, Telecom
New Zealand, PLDT, NTT, iBasis, Etisalat, Telkom South Africa, SFR
objective : facilitate the development of interconnected IP services




facilitate efficient migration of voice services as well as multimedia services to IP
take into account the interconnection requirements for various players and services
help select standards among multiple alternatives, in various situations
contribute to explore and to promote the IP-based services innovation
approach




business oriented (retail and wholesale)
pragmatic, focused and fast-paced
open and relevant to all players
I3 forum members to implement their own
recommendations independently
i3 forum and the carrier industry



not a standardization body, not a commercial alliance
open to liaise with other industry bodies (e. g. GSMA, ETSI…)
open to additional members who support the above objectives
phase 1: voice bilaterals
business aspects
 maintain (improve) current quality levels, service
features,
 make sure existing business models can be
transitioned
technical recommendations
 network architectures allowing a variety of
interconnection models
 designed to enable trusted, secure and QoS
compliant bilateral voice interconnects over IP
 based
on
existing
standards
&
recommendations
deliverables: operational documents
available and open to all


interconnection models
interoperability test plan
template for migration
70% of international
traffic
what we have delivered
existing bilateral voice business
model still possible
 revisit the service definition of bilateral
voice
 base on calling party pays scheme
guarantee or exceed existing TDM
quality levels
 multiple quality levels deriving from
combinations of technical elements
 two quality levels worked out in the
document


top quality
best effort
service features migration
 enhance present set of capabilities




voice call / IDD
toll free numbers and home country,
voice ISDN
fax calls, DTMF / modem support
ready for wide-band codecs
Existing model still
possible
technical aspects
minimum set of QoS parameters



IP parameters:
voice/media parameters:
network parameters
accounting and charging capabilities
security issues


border functions implementation strongly recommended
encryption: IPSec encryption of signaling flow for
public-oriented interconnection only
signalling protocols: two protocols selected


SIP protocol (IETF RCF 3261): specific profile defined
ISUP enabled SIP profile
media functions supported




voice conference calls;
DTMF support;
fax connections based on T.38 protocol;
modem connections
interconnection models for bilateral voice
private-oriented interconnections
 no unidentified third party is able to affect the
bilateral voice service
 3 options depending on type of link
 potential for highest quality and network security
 can replace existing TDM-based interconnects
public-oriented interconnections
 VoIP traffic mixed with other IP traffic coming from
the public internet
 2 options differentiated at the interconnection layer
 service performance and quality can be affected
 lower cost (resources shared with other services)
 lower provisioning time (no need to set-up an ad-hoc link)
keeping the value in voice
moving forward
implement phase 1 recommendations and work on phase 2
expand the i3 Forum
explore other aspects and servic
 Involve more carriers & remain
agile
 Raise i3Forum profile
 rest of voice (traditional models)
 new business models
 IP-based routing & addressing (incl.ENUM
 other services
liaise with other bodies and forums
establish cooperation with the GSMA and the
IPIA
