The schedule organized by Richard Wein (nic.at) is quite impressive. Thursday will be dedicated to political issues and features prominent speakers from Austria, Europe, ICANN, IETF and ITU. Friday will be more technical and will have presentations and lectures on DNS, ENUM, DNSSec, IPv6 and SPAM.
Although most of the participants will speak German, a simultaneous translation in English will also be provided. This will open Domain Pulse to English speakers.
Note: Another reason may be ;-) "German is the common language separating Austrians and Germans (and the Swiss)" - Friedrich Torberg

I met Jeff again at the airport in Nice and my flight was delayed also because of the bad weather conditions in Vienna. I finally ended up at home 3 hours late and this morning my house looked like this:

In this news story, Google denies entering the VoIP space
But here are some other sites fueling the Google VoIP speculation...
So it is still mere speculation?
Jeff Pulver tackled the issue from another side:
A quick check at the Spring 2005 VON delegate database shows that a number of Google executives in fact will be joining us in San Jose in March.
Maybe Google is 'just interested' in VoIP. I suspect there may be something more to this. :-)
The where a lot of opinions, but finally Tom Keating got it right.
Finally the story was released one week later at The Times:
The company behind the US-based internet search engine looks set to launch a free telephone service that links users via a broadband internet connection using a headset and home computer.
Mr Hewitt from Ovum said that a Google telephone service could be made to link with the Google search engine, which already conducts half of all internet inquiries made around the world. A surfer looking for a clothes retailer could simply find the web site and click on the screen to speak to the shop.

ETSI DTS 102 172 V2 "Minimum requirements for interoperability of ENUM implementations"
contains general guidance on (User) ENUM implementations as defined in RFC3761 and in ETSI TS 102 051 “ENUM Administration in Europe” and the specification for:
- The format, contents and meaning of the information in the NAPTR records that are held by the ENUM Tier 2 Nameserver providers and accessible by DNS.
- The ways in which ENUM client software should interpret and act upon information obtained from NAPTR records.
- The same ENUM client software to work with NAPTR records generated by different national implementations and this in turn will enable applications that use ENUM to access details of ENUM subscribers in more than one country without additional modifications.
- Organizations to function as ENUM Registrars and ENUM Tier 2 Nameserver Provider in more than one national implementation.
The present document is Version 2 of the Technical Specification (TS) and incorporates already some results obtained from trials performed in some countries. It may serve therefore also as a basis for first commercial deployments, keeping in mind that still not all enumservices are available as IETF RFCs and registered with IANA.
The intention is to review this document based on the experience gained from future implementations and if necessary.
ETSI DTR 102 055 "Infrastructure ENUM"
This document identifies a range of issues which occur if providers of communication services and networks (called Communication Service Providers (CSP) within this document) consider using the concepts developed in RFC 3761 (ENUM) for infrastructure purposes. Such an approach would result in the application of the ENUM concept to the provision of information for routeing (both internally and for the interconnection of networks – also called peering), including information for number portability, freephone and other number or address translation capabilities, SMS and MMS, etc.
It considers the likely steps along the way and where possible, identifies alternative options and approaches. It will specifically identify:
- issues which occur if providers of IMS-based NGNs consider peering traffic with each other via Points-of-Interconnect based on IP technology, by using E.164 numbers to address end-points they are hosting for their subscribers,
- issues which occur if providers of IMS-based NGNs consider peering traffic with other providers e.g. IMS-based PLMNs and also with providers on the Internet.

Yankee Group VoIP Marketshare
I have also stated various times that providing fixed line PSTN replacement services only is NOT enough for VoIP providers, especially in a shrinking market. What is needed is new, innovative, nomadic and mobile IP Communication services including vioce, video, IM and presence. The future will be personal, mobile, wireless, nomadic and portable communications.

P2P communications started with file sharing for audio and video (e.g. napster, kazaa,
bittorrent, ...). Skype introduced the principle to IP real-time communications and the success of Skype caused some of the SIP-Gurus (e.g. Henning Schulzrinne and Henry Sinnreich) also to think about P2P SIP.
Viral communications derives directly from the end-to-end
principle on which the Internet is based — the intelligence is in
the end nodes, the network itself maintaining as little state as
possible. As defined, the Internet is not optimised for any
particular use or communications requirement, it merely
forwards packets on a ‘best-effort’ basis. This principle kept
the Internet open to innovation by reducing the architectural
impact and cost or risk imposed on the development of any
new application; applications could start small and propagate
by pure popularity, no core change was needed, and no
innovation had to be debugged well enough to ensure that it
had no adverse impact network integrity.
Gordon Cook from Cook Report pointed me recently to a paper on Viral Communications from David P. Reed and Andrew Lippman (MIT Media Laboratory Reseach), which was written already more then one year ago. David is also blogging together with Bob Frankston and Dan Brincklin at satn.org
From the abstract:
Communications are poised to become personal, embedded features of the world around us. New technologies allow us to make wired and wireless devices that are ad hoc, incrementally installed and populous almost without limit. They need no backbone or infrastructure in order to work — instead, they use neighbors to bootstrap both bit delivery and geolocation. This re-distributes ownership of communications from a vertically integrated provider to the end-user or end-device and segregates bit delivery from services. Communications can become something you do rather than something you buy. This new research program explores the enabling principles for these viral communicators and will demonstrate their fundamental ability to scale and automatically configure themselves through a diverse set of applications including live voice, secure transmission, lowpower/high-availability signaling, and sensors with a sense of place. We will address this in economic and social cases that include telephony, media distribution, safety and emerging markets.
I contacted David for more information and he pointed me to another document on from A. Lippman and A. Pentland, which deals with the broader embedding of the viral work in human networks (the bigger vision) and is called "Organic Networks":
The topic of organic networks derives from the confluence of two distinct bodies of research that have been proceeding independently in the MIT Media Lab for the past several years — ‘Viral Networks’, which focuses on the enabling technology underpinning end-to-end, grassroots communications systems, and ‘Influence Networks’, which encompasses ways that both first-world and third-world societies bend the technology of easy connectivity to suit their own economic, cultural and social interests. While the general method of research in the Media Laboratory (semi-autonomous groups following largely independent research tracks) implies that these two themes are somewhat segregated, their intersection carries implications and lessons in and of itself that are too strong to be ignored — hence this co-ordinated set of papers.
This paper and the set of papers mentioned above from this cross MIT sponsored programm have been published in the October 2004 issue of BT Technicology Journal
All the documents (about 27 papers) may be downloaded.
David also pointed me to the group website and the cross-MIT sponsored program

European telecom operators will be hit the hardest by the fast and accelerating uptake of Voice over IP (VoIP) services such as Skype that route voice calls over the internet - both fixed and mobile operators, according to a newly published study from research firm Evalueserve.
The reason is that European operators are relatively highly exposed because calling and roaming rates, as well as the share of roaming calls, is higher, and local calls are charged by the minute.
In contrast, the study found that the flat monthly telephony fee model prevalent in countries such as the US was less likely to be affected by VoIP providers.Andy argues that:
I actually think the RBOC's flat rate customers are prime to switch. Here's why. They are early adopters, not laggards. Over time they want the best. They are price savvy, so VoIP offers appeal to them easily, and they likely already have the features they want now available with VoIP. By shedding the local line costs they save at least $10.00 or so, and avoid taxes. That's why the RBOC's have to be concerned about the Vonages and CallVantages of the world.

Steven Forrest's weblog about the often troublesome intersection of regulation and technology innovation:
Troublesome is true - I should send him a T-shirt ;-)
While ENUM - they tying of telephone numbers to Internet Protocol addresses, a potential boon to the growth of Internet telephony - is described as "stalled" in the United States, it is being rolled out in Australia "with a light regulatory hand," according to a story published April 12 in Washington Internet Daily, an online newsletter. One would hope U.S. regulators would watch and learn from the Australians.
The story isn't available from the newsletter's website, but is available via Lexis-Nexis. Here is a very brief excerpt...
Austria is ready to be "first to jump the cliff" into commercial e-numbering (ENUM) services, Internet Foundation Austria (IPA) Chmn. Michael Haberler told us. A 2-year commercial phase will launch this year, overseen by the country's Broadcasting & Telecom Regulatory Authority (RTR) and with NIC.at providing registry services, said Georg Serentschy, RTR managing dir.-telecom section. The plan flies in the face of claims ENUM isn't ready for prime time in Europe because technical and regulatory issues aren't resolved. Because no one knows how ENUM will develop, Serentschy said Thurs., regulators are exerting a light touch.U.S. regulators ought to watch what Australia is doing - and not doing - about ENUM, and learn from it.
ENUM activities don't fall within Austria's telecom act because it specifically excludes domain names from RTR's authority, Serentschy said. However, he said, early on the govt. applied for .3.4.e164.arpa for its ENUM domain name because it recognized the relationship between telephone numbers and ENUM services. As the domain owner, RTR sets rules for its use.
Austria ran an ENUM trial, but it's shifting to a commercial rollout in the late 3rd quarter or early 4th quarter, Serentschy said. The phase is limited to 2 years because "one of the things we want to find out" is what the ENUM service will look like, he said. NIC.at will have the right to operate the registry during that time, he said, but if ENUM proves popular, others may be allowed to bid on providing registry services. Extensive discussion in the U.S. has concerned whether there should be multiple registries as well as registrars. Austria is most likely to go with a single registry and several registrars, Serentschy said, but it depends on the market. It's not clear who will be most interested in ENUM - consumers, businesses or both, he said. Until that's known, the govt. doesn't want to overload the emerging service with regulatory constraints, he said.
The only regulatory action the govt. has taken is to dedicate a new number range - 780 - for ENUM services, Serentschy said.
As Computer Business Review reported April 7:
Public deployment of ENUM, the three-year-old standard for using telephone numbers over the internet, is still a way off in the US, despite the fact that many people think it will be an essential component of widespread voice over IP adoption.
The US government came out in favor of accelerating ENUM plans in February 2003, but little has happened since, as the telecommunications, cable and internet industries try to hammer out the details of how implementation should happen.
Interested parties organized into a group called the ENUM Forum have agreed that the best way to introduce ENUM in the US would be to form a limited liability corporation, which would receive contractual authority to run ENUM from the government.
But there is still disagreement over how the ENUM registries contracting with this LLC would be required to operate. The complex issue takes into account political boundaries and competition and revenue concerns.
AusRegistry requested a delegation for the ENUM domain name zone corresponding with the Australian E.164 country code +61 from RIPE NCC. This delegation will enable AusRegistry to commence the trial of ENUM in Australia.
The ITU-TSB confirmed that the request for ENUM delegation of code 61
has been authorized by the concerned national Administration and the
delegation may proceed when RIPE NCC receives formal confirmation from the
Director of TSB.

My topic is:
100+ Years vs. 10+ Years
Tuesday, January 25, 2005, 11:15am - 12:00 The traditional network supports services that the government has seen as important, such as emergency services, wiretapping, and lifeline services. Should VoIP be subsidizing these activities in the same way? Or should new structures be put in place?
· How have the requirements changed thanks to wireline and wireless?
· What is the expectation for integration technology?
· Are the differences in the countries’ standards forcing delays?
· Will a common infrastructure be needed? How should it be paid for?
Good questions, any answers? (especially for the last one ;-)
Forbes.com is trying to find out what normal people are thinking about this by launching a poll:
What will you use for your Main Phone Line this year?
The results are very interesting sofar:
From approx. 2000 votes
43% will keep their traditional landline
24% will use cell phones (this may by US centric)
only 2% will switch to cell phone !!?
12% will continue to use VoIP ! (Skype?)
and 13% is planning to switch to VoIP !
If this is true, 25% will use VoIP as Main Phone Line End of 2005!
Even if one considers the vote somewhat biased (non Internet users are not voting), this is still astonishing.
