How Do We Define 'SIP' for Telecom In 2014?

"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»

iPhone 6 VoLTE Will Disrupt the Mobile Industry

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»

IP Network Transformation: Waiting Costs More Than You Think

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»

Can We Create a Secure Caller ID For VoIP?

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»

Why the Opus Codec Matters - Even if You Don't Care About Audio

What makes the Opus codec so interesting? Why is there such a buzz about Opus right now? If you are not in telecom or doing anything with audio, why should you even remotely care about Opus? In a word... Innovation! And because Opus has the potential to let us communicate with each other across the Internet with a richer and more natural sound. You will be able to hear people or music or presenters with much more clarity and more like you are right there with them. more»

Moving Beyond Telephone Numbers - The Need for a Secure, Ubiquitous Application-Layer Identifier

Do "smart" parking meters really need phone numbers? Does every "smart meter" installed by electric utilities need a telephone number? Does every new car with a built-in navigation system need a phone number? Does every Amazon Kindle (and similar e-readers) really need its own phone number? In the absence of an alternative identifier, the answer seems to be a resounding "yes" to all of the above. more»
