VoIP

Voice-over-Internet protocol (VoIP) is a protocol optimized for the transmission of voice through the Internet or other packet-switched networks. VoIP is often used abstractly to refer to the actual transmission of voice (rather than the protocol implementing it). This latter concept is also referred to as IP telephony, Internet telephony, voice over broadband, broadband telephony, and broadband phone. VoIP can facilitate tasks and provide services that may be more difficult to implement or more expensive using the PSTN. Examples include: The ability to transmit more than one telephone call over the same broadband connection. This can make VoIP a simple way to add an extra telephone line to a home or office. Conference calling, call forwarding, automatic redial, and caller ID; zero- or near-zero-cost features that traditional telecommunication companies (telcos) normally charge extra for. Secure calls using standardized protocols (such as Secure Real-time Transport Protocol.) Most of the difficulties of creating a secure phone connection over traditional phone lines, like digitizing and digital transmission, are already in place with VoIP. It is only necessary to encrypt and authenticate the existing data stream. Location independence. Only an Internet connection is needed to get a connection to a VoIP provider. For instance, call center agents using VoIP phones can work from anywhere with a sufficiently fast and stable Internet connection. Integration with other services available over the Internet, including video conversation, message or data file exchange in parallel with the conversation, audio conferencing, managing address books, and passing information about whether others (e.g. friends or colleagues) are available to interested parties. Advanced Telephony features such as call routing, screen pops, and IVR implementations are easier and cheaper to implement and integrate. The fact that the phone call is on the same data network as a users PC opens a new door to possibilities. Read the full background at VoIP Wikipedia

HD Voice Really is Great

Listen for half a minute to a demo of a high-bit-rate codec and you expect they will transform our industry. The difference is like a CD with great headphones versus a little transistor radio. Suddenly, you realize just how awful the sound is on your regular telephone. Who wouldn't want their call to sound dramatically better was my first reaction. When Thomson and some of the cable folks discussed plans, I was enthusiastic. Years later, nearly no one is taking advantage... more»

What to Do with Skype?

Without rehashing the mainstream headlines, it's clearly on the table now that eBay has given up trying to create synergies with Skype, so the focus now is on making the best of things as distinct entities. The preferred route for eBay would be to keep Skype and recoup their investment via an IPO sometime next year. That would certainly bring an end to things with both parties leaving on a high note. Of course this hinges heavily on the state of capital markets... more»

Project GhostNet: Canada (and Google) Save the World from Cyber-Spying - Again!

While most people I know are at either VoiceCon or CTIA this week, this one is worth staying home for. Also, I'm sure all the Skype followers are focused today on the news about working with the iPhone -- and that IS a big story. However -- for very different reasons -- I'm sure you'll find this one of interest too. This was a front page story in today's Globe and Mail, and no doubt many other Canadian dailies... more»

Will ENUM Deliver?

ENUM (E.164 NUmber Mapping) is a technology that has been around for a little while that has promised much and, so far, delivered little to the average user. As Nominet has recently been awarded the contract to administer the UK 4.4.e164.arpa delegation, I thought it was time that I put my thoughts on this subject down in writing. I'm going to cover the potential of ENUM in the telecoms industry and what it could mean to you, along with how it is currently being used and what potential security issues surround ENUM. more»

Exploring the Roots of Wireless Spectrum Controversy (eComm Panel)

Earlier this month, I had the opportunity to attend the The Emerging Communications (eComm) 2009 conference in San Francisco which was packed with 3 days of fascinating conversations about the future of communications. I absolutely enjoyed talking to various speakers and attendees giving me a deep level of appreciation and perspective on technical, commercial and political issues at hand -- and what is likely to come in the next few years. And speaking of politics, Lee Dryburgh, who founded eComm in early 2008, has generously allowed us to share with you a fascinating panel discussion which took place on day 3 of the conference called "Spectrum 2.0 - What's really happening?" more»

Why You Needed to Be at eComm 2009

I've been posting photos and snippets during eComm 2009 this week, but composing my overall impressions has been another matter. Sitting through 3 days mostly filled with continuous 15 minute presentations is a surefire recipe to fry your brain, and most people I talked to were topped out well before things wrapped up Thursday night. It's information overload of the highest -- and best -- order... Here's my top-line takeaway, and reading the rest of this post is really just detail. But it's detail you'll probably love if you really want to know what you missed... more»

Will Martin Geddes and Telco 2.0 Turn Around BT?

British Telecom (BT) is hurting because the wireline phone business is inevitably declining. Their new hire is one of the world's most interesting thinkers on possible new businesses for telcos. Martin has been part of the Telco 2.0 group at STL Consultancy, the best small group of European analysts... more»

Ten Telecom Tsunamis

The telecom industry five years from now will be unrecognizable. The creative destruction of the Internet broadly writ will be even greater than it has been in the last decade. The major telcos, the major television networks, and the major cablecos -- if they still exist at all -- will have very different revenue models than they have today. That's the good scenario... more»

An Interview With Richard Whitt, Google's Washington Telecom and Media Counsel

The following is the transcript of our phone conversation and the audio recording of the interview. more»

VoIP Security Predictions for 2009

Here are my VoIP and Voice security predictions for 2009, limited to just a few, key predictions... The poor economy will slow the adoption rate for VoIP and Unified Communications (UC). This will continue to limit the size of the enterprise VoIP deployments for potential hackers to exploit. VoIP/UC will continue to be mostly an internal/campus application where the threat level for attack is low, so deployments will be largely secured along the same lines as other data network applications. more»
