VoIP: Beyond Digital POTS

I've been involved with VoIP technology since 1996. I've been a public advocate for wideband audio at least since 1997. And I've admired and supported a variety of companies using VoIP to provide innovative services and new user interfaces. But reflecting on the past decade, the only globally significant impact of VoIP has been on prices (by fostering arbitrage). Most VoIP telephony services are just digital POTS... more»

Frustrations with VoIP Phone Services

I ought to explain why I've suddenly gone cold on VoIP. It's just I've watched my own behaviour. I've grown tired of the inconsistency of PC VoIP calls, and instead I've reverted to using landlines, mobiles and Jajah (for callback). But I'm still using IM to set up many of those calls! The problem isn't unique to any one client - they're all proving unsuitable for business use with clients (which is most of my telephony needs covered). The worst of all seems to be Skype conference calling... more»

.Mobi Premium Name Auction Off to Wild Success at TRAFFIC in Miami

I'm in attendance at the the TRAFFIC EAST 2006 show, in Hollywood [Miami], Florida. There has been a lot of buzz here about the .Mobi top level domain, ranging from the talk of early registrants hoping to create the next big mobile portal to those that were keen to see implementations of mobile content. There was a domain name auction this evening where flowers.mobi sold for $200,000.00 (USD), and fun.mobi for $100,000.00 (USD) from a long list of domain names in the com, net, info, org, us and mobi extensions. more»

Security Experts Warn VoIP Attacks May Be Just Around the Corner

It's become a familiar pattern in online security. A groundbreaking way to communicate emerges, spreads like wildfire, and then hackers find a way to use it to their advantage. Security companies react--but not before the problem has succeeded in wreaking havoc. It happened with e-mail and is happening now with instant messaging and mobile devices.

The next area that could be targeted: Voice over Internet Protocol, or VoIP, which lets people make low-priced phone calls using the same technology that delivers e-mail. And the results could be just as damaging, if not worse, than with other technologies, some security experts warn.  more»

dotMobi Could Spur Wireless Web

Surfing the Web on a cellphone can be as difficult as surfing the ocean on a tiny board. Now, a company founded by Microsoft Corp., Google Inc., Vodafone Group PLC, Nokia Corp., and several other companies, aims to make it easier to browse the Internet on wireless devices such as cellphones or BlackBerries...

Many sites can't be displayed on tiny cellphone screens, and most would take a much longer time to download than on a PC. Mobile Top Level Domain aims to change that in part by setting up a new domain name specifically for wireless Internet Web sites called dot-mobi. more»

ENUM: Mapping the E.164 Number Space into the DNS

Many communications networks are constructed for a single form of communication, and are ill suited to being used for any other form. Although the Internet is also a specialized network in terms of supporting digital communications, its relatively unique flexibility lies in its ability to digitally encode a very diverse set of communications formats, and then support their interaction over the Internet. In this way many communications networks can be mapped into an Internet application and in so doing become just another distributed application overlayed on the Internet. From this admittedly Internet-centric perspective, voice is just another Internet application. And for the growing population of Voice over IP (VoIP) users, this is indeed the case... more»

Telecom Impact on Per-Capita GDP

My presentation at VON was focused on availability (aka presence) and contextually-aware communications, but I did begin with a brief mention of subjects I'm passionate about and I ended with my typical closing comments about telecommunications... Apparently this struck a chord with several people who came up to me afterwards asking about how they could help the spread of telecom to developing countries and did I have references for my statements about telecom is good for mankind? more»

Examining the Reality of Convergence

If there is one word in the telecommunications that has suffered from over-abuse for many years now, it's convergence. The term has been liberally applied to each successive generation of communications technology for their supposed ability to solve a myriad of service delivery problems within a single unifying converged carriage and service delivery solution. Unfortunately, the underlying reality has always been markedly different from these wondrous promises, and we continue to see an industry that deploys a plethora of service delivery platforms and an equally diverse collection of associated switching and service delivery technologies. One can't help but wonder at the collective gullibility of an industry that continues to herald the convergent attributes of each new generation of communications technology, while at the same time being forced to admit that previous convergent promises have never been realized. more»

Industry Giants Embarking on Internet Frontiers

In a recent press release, Alan Harper says: "The aim of the initiative is to accelerate the rollout of Internet products and services specifically designed for mobile devices as well as to ensure far greater operating simplicity for mobile subscribers across the globe. This venture should build on the considerable trust that exists in the mobile community between subscribers and operators." What is this initiative you ask? A new wireless protocol? A new wireless association? Not exactly! more»

Exposing 9 Myths About IPv6

This is a special two-part series article providing a distinct and critical perspective on Internet Protocol Version 6 (IPv6) and the underlying realities of its deployment. The first part gives a closer look at how IPv6 came about. This part exposes the myths.

Good as all this is, these attributes alone have not been enough so far to propel IPv6 into broad-scale deployment, and consequently there has been considerable enthusiasm to discover additional reasons to deploy IPv6. Unfortunately, most of these reasons fall into the category of myth, and in looking at IPv6 it is probably a good idea, as well as fair sport, to expose some of these myths as well. more»
