Commercial Models for VoIP>>
 

Mobile telephony, the Internet and oversupply are contributing to the rapid demise of legacy commercial models for telephony. Voice over IP (VoIP) has in the meantime undergone several versions, from the long distance and international PSTN bypass to PSTN gateway service and the use of VoIP in isolated enterprise IP network islands.

We specify the criteria by which real VoIP can be separated from various PSTN emulations that may have some hidden IP plumbing, but do not expose the users to any of the benefits of IP.

Of the many disruptions caused by the Internet, P2P SIP telephony is one alternative that does not require any other infrastructure, but the Internet 'as is'. This may put in question many of the consumer oriented VoIP networks that are based on costly infrastructure and the suppliers of VoIP infrastructure.

>>11h40 | 12h05 Keynote Address:
VoIP - Revolutionising the Telecoms Industry>>
  Thomas Vasen, Telio

>>12h05 | 12h30 Keynote Address:
Future of IP in the business of operators/carriers>>
  The days of IP being the sideshow in telecoms networks is over. The next decade will see a wholesale transformation of telecom networks to IP based infrastructures. What is driving this change and why will it really happen this time rather than being another false technology promise. This presentation will explore the major drivers for IP in the network and explore some real world examples of network operators around the world who are implementing IP based network infrastructures for the customers of the future.
Mike Wilkinson, Alcatel

>>14h15 | 14h45 Keynote Address:
New tools for measuring customer perception of voice quality in VoIP networks>>
 

The introduction of packet-networks created a requirement for a new generation of measurement tools. Packet networks typically include; low-bit-rate coding, variable delay and time-varying performance. Traditional performance measurement methods such as intrusive frequency-response measurement are inadequate and do not predict the performance experienced by the customer.

A new generation of quality measurement methods have been developed over several years that can provide an accurate prediction of customer experience. Predictions are on the 1 to 5 MOS (Mean Opinion Score) scale and relate directly to the opinions given by people. The new methods include intrusive (active) testing, such as ITU-T P.862 PESQ, and non-intrusive (passive) testing such as NiQA, ITU-T P.562 CCI and psyVoIP. These software-based methods can provide accurate point measurements and continuous real-time monitoring of VoIP networks for: SLA management, MOS based alarms, rapid identification of service affecting faults and directed maintenance. This talk will introduce these new voice quality measurement methods and describe how they can be used to instrument practical VoIP networks.

>>14h45 | 15h15 Industry Statement:
High Availability as a key driver on a VoIP solution deployment>>
 

Moving from legacy telephony into VoIP changes some installation issues like availability, energy, cooling and cabing.

The purpose of the presentation is to bring awareness on some important details which, most often, are forgotten.

Changing the World: One Number At A Time>>
  Voice over IP is gaining well-deserved recognition in the U.S. and worldwide. The number of residents using VoIP in the U.S. is expected to grow to over 10 million by the end of 2007. In fact, a wide -- and rapidly growing array -- of carriers are launching VoIP services. It is no longer a question of whether or not VoIP will become prominent in communications, it now a question of when. Vonage is proud to be a leader in the market, and has set the benchmark, proving its value proposition to a marketplace starved for full-featured, cost-effective alternatives to the incumbent local exchange carriers.
Kerry Ritz, Vonage

>>17h10 | 17h40 Consultant Statement
Market Trends: The Convergence to IP>>
  Macroeconomic analysis of the Portuguese economy, and the steps to achieve sustained growth, stating the relevance of IT investment for the increase of productivity, fundamental for that growth. In this area, IP is definitely one of the emerging standards. In a context of evident convergence, issues such as IP Telephony and other complementary services (such as Video-conferencing over IP or IP Contact Centres) will be addressed.

VoIP an Internet Service like Electronic Mail?>>
  In last years the VoIP was the Internet Service that we eared most all over the Internet. Lots of players have been developing products around the world. They all started from the PSTN telephony perspective, which is not for sure the the approach of most of Internet services.

Therefore the VoIP service firstly was designed to use H323 a protocol that seems to inherits lots of the features of the PSTN network. Where the Voice Operators and PABX equipements were very important for supporting the voice service. Nobody could believe that a service over the Internet would depend on a Voice Operator, and special equipments to work.

Looking to the electronic mail, we understand that as soon as we are able to setup a server with an SMTP service active, and if the DNS is well configured, we can immediatly start to send and receive mail messages. Why that will be so different for the VoIP service. So why would is so difficult for two people with an Internet connection to phone each other without depending on Voice operators or a kind of PABX equipement now called a Call Manager. Worst, the majority of call managers are not prepared to work together, and transfer call between then, especially when two vendors are involved.
Is that natural?

The SIP protocol, proposed by the IETF, was in fact what we were waiting for the Voice over Internet. Now the SIP protocol is gaining momentum, and several implementions are coming out. Most of them in terms of free software projects like happened before in the Electronic Mail. The SIP service also can be defined in the DNS, as the SMTP service, and so it is possible to discover phones under a certain domain, in the Internet with public or private IP addresses.

What will be new in this VoIP world is the introduction of users after the phones. Till now every body is used to make a phone call to phone device, and in the future we will make phone calls to users, that are willing to receive phone calls in a certain phone device. Let's call a person by its email address user@domain.com. Which service is going to locate the user? The LDAP service of that domain will be the most approapriate choice. Then in the LDAP service each user will have an SIP URL that points to a phone device. So we will be able to call the user wherever he will be willing to receive calls in a phone device.

In summary the VoIP Service will be a combination of SIP, DNS and LDAP, and in convergence with common data, the SMTP and IMAP protocols of electronic mail will be important to store and manage voice messasges when the user are not available to establish a phone call.
