In the beginning there was silence; then, silence begat communication, and communication begat more communication and, ultimately, group communication formed and begat a primordial "network" of communication that gradually and inevitably increased in effectiveness and complexity: there were only signal fires at first but, then, there were cave drawings, carrier pigeons, shouting from hill-tops, smoke from fire, lines of cannon fire, the telegraph, Alexander Graham Bell, and, finally, the network of networks known as the Internet. But, is that it? Is there not something more impressive in its impact upon communication than the Internet? What more might one desire than the dynamic wonders of the Internet, you ask? Well, what about ENUM? "E-What!?" more
Do you know someone who deserves recognition for helping build the Internet in their region or country? Or someone who made the Internet more secure through the work they've done? Or someone who made some major technical innovation that made the Internet faster or better? more
5G represents a threat to the level playing field and innovation of the Internet. It is the new face of the battle over network neutrality. At its inception in the 19th-century, the talking telegraph (AKA the telephone) was an amazing feat of engineering using analog technology. One could speak into a microphone in one city and be heard in another city. Accomplishing this required a very large investment in technology. The customers were consumers of the service. more
The last few weeks have reinforced the importance of modern communication networks to societies. Health care providers, schools, governments, and businesses all rely on networks that enable us to connect and collaborate remotely. Had we encountered a similar pandemic ten years ago, we would not have been able to continue our activities on the level that is possible today. more
Consumers are embracing VoIP services now more than ever as they get used to calling over Internet application services such as Skype, Facetime, and Google Hangouts. Market Research Store predict that the global value of the VoIP services market is expected to reach above USD140 billion in 2021, representing a compound annual growth rate of above 9.1% between 2016 and 2021. more
In just the last two weeks, there were three major DNS outages between Google, Microsoft Azure, and Fonality. But only one of these companies was able to make even bigger waves with the way they handled their blunder. Fonality, who sells VoIP services and business phone systems, offered a very rare and transparent analysis of their outage. In a detailed statement from Chief Marketing Officer Jeff Valentine, readers were given crucial insight on how to prevent the same mistakes from happening to other companies. more
With companies shifting away from on-premises and "traditional" telecom networks to Internet-based protocols - such as Voice Over IP (oIP) - the market for critical communications infrastructure - most notably SIP trunking - is on the rise; not only multiple failover sites but cloud-based SIP-as-a-service solutions are now popular options. However, there's a caveat: problems unique to SIP systems that can cause IT headaches if you're not prepared. Here are three of the most common. more
Following my comments about the iPhone VoLTE announcement I had an interesting conversation with Andy Huckridge from Gigamon, a company that provides intelligent traffic visibility networking solutions for enterprises, datacentres and service providers around the globe. An interesting concept that we discussed was the 'triple challenge of network transformation'. The three elements of this challenge are... more
"What is a minimum set of specifications that a vendor must implement to be able to say that it is SIP-compliant?" A friend asked me that question and my response was: "It depends." and even more unfortunately:
"I don't know." It turns out to be a challenging question to answer... and it led me to ask: "How do we define what "SIP" is for telecommunications in 2014? How do we help vendors move their products/services to be based on SIP? As we talk about "turning off the PSTN" and "moving all telecom to IP", how can we make it easier for companies to switch to using SIP? more
As far back as 2011 we predicted that Apple would eventually enter the voice market. We indicated at that time that it was just a matter of time -- in the end it took another three years... While it didn't happen at Christmas that year the company is now ready and will use the VoLTE service to enter this market, which will make it possible to replace Telstra with any other mobile operator around the world... he telcos are not ready for this. While they should be seen as the leaders in the voice call market they are too preoccupied with protecting their traditional business and it is companies like Apple and Samsung who are now leading the charge. more
Few CSPs would dispute that IP-based mobile communications are the future. But some still see little reason to replace TDM switches that, on the surface, cost them little beyond energy and housing expenses. At the recent Neustar Interactive Insights Summit, telecommunications experts Jennifer Pigg, Vice President at Yankee Group, outlined the conundrum -- and revealed the cost of doing nothing is higher than many think. more
What is the impact of IPv6 on telecommunications, VoIP, unified communications, etc? Why should telecom operators care about IPv6? What VoIP systems already support IPv6? What efforts are underway within organizations like the IETF and the SIP Forum to ensure that telecommunications can work over IPv6? more
Interested in working on an open standard for "secure Caller ID" for voice-over-IP (VoIP)? If so, the new "Secure Telephone Identity Revisited (STIR)" working group was just officially chartered within the IETF and the mailing list is open for all to subscribe. more
The 87th meeting of the Internet Engineering Task Force (IETF) in Berlin, Germany, concluded on August 2, 2013. IETF Chair Jari Arkko recently published his summary of IETF 87 on the IETF Blog highlighting what he felt were some of the more important aspects of what was a very successful IETF meeting. I also had the privilege of interviewing Jari on video about the meeting. more
Can we create a "secure Caller ID" for IP-based communications, a.k.a. voice-over-IP (VoIP)? And specifically for VoIP based on the Session Initiation Protocol (SIP)? Can we create a way to securely identify the origin of a call that can be used to combat robocalling, phishing and telephony denial-of-service (TDOS) attacks? That is the challenge to be undertaken by the "Secure Telephone Identity Revisited (STIR)" group meeting tomorrow morning, July 30, 2013, at 9:00 am in Berlin, Germany, as part of the 87th meeting of the Internet Engineering Task Force (IETF). more
