Points to be discussed
How multimedia can help e-commerce?
How telephony and e-commerce will be
integrated?
How the Network Convergence will help
services that drive e-commerce?
What’s V-Commerce?
What’s a Voice Portal?
How can it be related with Internet?
How multimedia can help
e-commerce?
“Click to Talk” Service
Someone browsing an e-commerce site
clicks a hiperlink to talk with an operator.
A voice over IP session is established
between the PC and the operator.
The operator can be in a call center
(a “Web Call Center”)
The operator talks with the customer and
remotely assists him navigating through
the site.
Click to Talk and e-Commerce
It helps to give confidence to the
customer, clarifying doubts.
Can be fundamental in the sale process.
It is totally adherent to the “Next
Generation” Converged Voice over IP
Network
...and what is V-Commerce?
V-Commerce stands for Voice Commerce
It is based in a totally automated dialog
between the customer and the system.
It allows the user to access the system
through a voice terminal or though a
multimedia terminal.
It is totally adherent to the “Next
Generation” Converged Voice over IP
Network
Convergence of what???
Today there is a convergence trend:
Media Convergence: Multimedia
Terminal Convergence: Computer, TV, Video-game, Celular
Phone, PDA...
Providers Convergence: Mobile and Internet, CATV and
Internet, Telephony and Internet, Internet Access and Content
Provider, Content and Application Service Provider
Services Convergence : Several Integrated Services (ex:
Unified Messaging, Multimedia Conference)
Network convergence: Telephony and Data
Network Convergence
Trend to converge Telephony and Data
to a single network.
Target Network: A network based on IP
with controlled and Differentiated
Quality of Services.
Why IP?
-Internetworking
Internet Protocol
The only protocol present in the access
and in the core of the network
Allows transport of any media
Allows a cheap corporate and
residential Multimedia Terminal: the PC
Why to converge?
Forecasted Growth: Data and Voice

Convergence of Telephony and
IP Networks:
Transport using Voice over IP (VoIP)
Use of Interworking Gateways
(to interwork with the legacy)
Use of VoIP terminals (CPE)

Business Size
Kelsey Group: “Voice Portals will generate
US$ 12 Bi up to 2005 through advertising,
e-commerce, HW+SW sales and telephony
service (from this amount, US$ 4.6 Bi in
advertising and transactions)”. There will be
more than 128 million voice portal users
by the end of 2005.
Data Corp.: “In 2004, 600 Million users will
connect to Internet through PCs, but
1.4 Billion will connect through mobile phones,
and other 1.4 Billion through black phones”.
Justificatives for voice-based access
Easier access to a telephone than to a
computer connected to the Internet.
Overwhelming growth of the mobile phones
Telephones can be used anywhere
The voice interaction improves navigation,
since minimizes the physical limitations of the
keypad and display.
Allows access to disabled people
WAP Integration
Users can choose between answering via
keypad, touch screen or via a voice
command
Users can access the Internet using voice
sinthesis, pre-recorded audio and speech
recognition, being possible to complement
the interface through the keypad and the
small display.
The voice interaction can help the WAP
browser.

Conclusions:
There is a trend to converge to IP due to cost
reduction and possibility of new services
The Open Packet Telephony (OPT) allows
introduction of services independently of the call
control layer and transport layer
Voice Portals use voice browsers based on
voice synthesis and speech recognition for
navigation
Voice browsers are a kind of Media Server in
the OPT architecture
