IDG Contributor Network: SIP trunks are more reliable than a PRI T1

Computer Hardware

Are SIP trunks as reliable as an ISDN PRI T1?

I’m asked this question a lot, so I thought it’d be a great blog topic.

I don’t think you are as concerned with this as the amber lights in the server room… But if you are making any changes to your company’s phone system, I’m assuming this question is on your mind.

The simple answer is… no. SIP trunks are not as reliable. They are more reliable than a Primary Rate Interface (PRI). But it has nothing to do with the public Internet.

IDG Contributor Network: As the iPhone turns 10, should we celebrate?

Computer Hardware

The iPhone just turned 10 and Apple sold 1.2 billion of the device which has transformed our lives, and reshaped the world economy into the “app economy.” The transportation industry has been deeply disrupted by Uber, and Facebook has redefined advertising while Airbnb has revamped hospitality. It will take years to grasp the profound change triggered by mobile devices on our society, how it has affected our relationships with our loved ones and how it has impacted the way we perceive the world around us, think and act.

If we just look at the bottom line, the app economy has failed to deliver economic growth, and unlike earlier technology revolu…

IDG Contributor Network: Fix poor VoIP call quality with a dedicated circuit

Computer Hardware

This is a bummer but I’m going to say it.

Getting a huge fiber Internet connection may not do anything to help your company’s VoIP call quality.

Assuming everything is squared away on your LAN, the most common causes of poor call quality are latency, packet loss and jitter; None of which can be controlled over the public Internet, no matter how much bandwidth you throw at it.

“But what if we have a 1G dedicated Internet connection?” Sorry, it’s not immune.

“But what if it’s fiber from a Tier 1 provider?” Your call quality is still high-risk.

IDG Contributor Network: Twilio does speech recognition and understanding, the right way

Computer Hardware

We’ve all had horrendous experiences with voice recognition when calling a support center – I’d like to think that it’s just me with my slightly unusual Kiwi accent, but everyone I talk to has similar stories of getting exasperated at an automated call center that hopelessly gets even the most basic speech recognition exercises wrong. It’s a sad reality of the modern world that organizations try to shoehorn users into solutions that aren’t yet fit for purpose, just to save some costs.

The world of communications has been the focus of Jeff Lawson for the past few years. Lawson is founder and CEO of Twilio, the company that offers a modula…

IDG Contributor Network: Twilio jumps on the serverless bandwagon

Computer Hardware

News from the second day of Twilio’s annual developer conference, Signal. While yesterday’s big news focused around end-user functionality (in particular speech recognition and understanding), today’s news is more down in the weeds but no less important for a company at the cutting edge of the developer experience.

You see developers are, by nature, tinkerers and like to experiment with new stuff. Sometimes this is simply professional interest, but often it’s because of an almost pathological desire to do things effectively, efficiently and elegantly. A case in point is the current developer move towards serverless technologies. First commer…

IDG Contributor Network: Going interstellar with Microsoft Cosmos

Computer Hardware

At Microsoft’s Build developer conference last week, the company announced Cosmos DB, a new cloud database offering that, if you believe the hype, entirely changed the database game. Before reelecting on what this means for developers and organizations, it’s worth taking a look at what Cosmos is.

Cosmos is a schema-free database service built with the aim of delivering high performance, fault tolerance, automatic indexing of data and truly globally distributed scalability. Cosmos is, at least in part, the evolution of Microsoft’s previous DocumentDB offering. DocumentDB was Redmond’s first foray into the NoSQL world. And while DocumentDB was…

IDG Contributor Network: Xero breaks through its glass ceiling: customers, revenue and cashflow

Computer Hardware

It’s fair to say that no one has been covering Xero longer than I have. I first talked to its co-founder and CEO, Rod Drury, long before the company launched a product. Trawling back through my emails and I discovered that we first talked about his vision 10 years ago to the day. (Rod, we really should have a celebratory beer!) I can’t imagine he’ll be celebrating the milestone, but it does go to show just how long Drury has been on this journey.

When it was founded, Xero took a very unusual path, listing on the New Zealand Stock Exchange before it even had a real product and customers. Backed by some high-profile names, and with Drury’s masterful m…

IDG Contributor Network: Catching up with Adaptive Insights and ruminating over the future

Computer Hardware

I’ve written in the past about Adaptive Insights, a Silicon Valley-based company in the corporate performance management (CPM) space.

CPM is a term that describes vendors who help organizations plan and model in order to get better insights over future organizational performance. Since I last caught up with the company, they have enjoyed 30% annual growth and now have 3,500 global customers spread across all the different financial/ERP products — from Xero at the smaller end of town all the way up to SAP.

IDG Contributor Network: Book Review: Practical Packet Analysis: Using Wireshark to Solve Real-World Network Problems

Computer Hardware

The overall equation is pretty simple: If you want to understand network traffic, you really should install Wireshark. And, if you really want to use Wireshark effectively, you should consider this book. Already in its third edition, Practical Packet Analysis both explains how Wireshark works and provides expert guidance on how you can use the tool to solve real-world network problems.

Yes, there are other packet analyzers, but Wireshark is one of the best, works on Windows, Mac, and Linux, and is free and open source. And, yes, there are other books, but this one focuses both on understanding the tool and using it to address the kind of problems th…

IDG Contributor Network: With HelloWorks, HelloSign finds the holy grail of digitalization

Computer Hardware

Innovation often displays an interesting progression.

In its first stages we see an existing process or system being cloned in another medium. While this might drive process efficiencies, that’s about all it achieves. But with enough vision, off that foundation we can see innovation progress to peripheral functionality and, eventually, to fundamentally reinvent the way things are done. Having watched eSignature company HelloSign for the past few years has been a good example of this.

I first came across the company many years ago when I was in the unfortunate position of having to send a fax internationally. For many people the very concept …
