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
Do you care any more about zillion different IM services? Do you care about the IM protocol wars that have plagued the usage of IM for the last years? Odds are that if you are an IM user like me, you probably don't. Why not? Simple... we've unified the IM services on the client side and basically stopped caring about the various services and protocols. I was reminded of this fact this morning when I received a message saying that an update was available for Adium on my Mac that solved a really annoying disconnection problem with Yahoo!Messenger. more»
Last week American Airlines launched their Aircell wireless Internet access on a limited number of flights. It didn't take long before a few folks tried to make voice and video calls (in violation of Aircell's terms-of-service according to their PR folks), and it didn't take long before someone figured a way around their voice/video blocking efforts. more»
In many ways, the emotionally charged debate on Network Neutrality (NN) has been a lot like hunting Unicorns. While hunting the mythical horse could be filled with adrenalin, emotion, and likely be quite entertaining, the prize would ultimately prove to be elusive. As a myth, entertaining; but when myths become reality, then all bets are off. The Network Neutrality public and private debate has been filled with more emotion than rational discussion, and in its wake a number of myths have become accepted as reality. Unfortunately, public policy, consumer broadband services, and service provider business survival hang in the balance. more»
After voting on the Comcast order today, Kevin Martin and his Democratic Party colleagues issued press releases telling us how they saved the Internet from Comcast's discriminatory practices, but they've failed to release the actual order they adopted and subsequently re-wrote. Commissioner McDowell wasn't allowed to see the revised order until 7:00 PM the night before the meeting. Rumor has it that high-level spin doctors are still trying to remove all the rough edges, inconsistencies, and factual errors. more»
Spam over Internet Telephony (SPIT) is viewed by many as a daunting threat. SPIT is much more fatal than email spam, for the annoyance and disturbance factor is much higher. Various academic groups and the industry have made some efforts to find ways to mitigate SPIT. Most ideas in that field are leaning on classical IT security concepts such as intrusion detection systems, black-/white-/greylists, Turing tests/computational puzzles, reputation systems, gatekeeper solutions, etc... We identified the lack of a benchmark testbed for SPIT as a serious gap in the current research on the matter, and this motivated us at the to start working on a first tool for that. more»
Here's my opening remarks from Media Access Project's Innovation '08 in Santa Clara this morning. A DVD will be available shortly. This was a lively discussion, with Google and Vuze on the case. Good morning and welcome. My name is Richard Bennett and I'm a network engineer. I've built networking products for 30 years and contributed to a dozen networking standards, including Ethernet and Wi-Fi... I'm opposed to net neutrality regulations because they foreclose some engineering options that we're going to need for the Internet to become the one true general-purpose network that links all of us to each other, connects all our devices to all our information, and makes the world a better place. Let me explain. more»
The SIP Center asked for an article which I finally wrote the weekend before last. My article was actually rather negative, but they published it anyway. Now I'm feeling a little guilty as there is an optimistic note I could have used as my conclusion. So let me try again... First let me summarize my problem. When SIP emerged in 1996, it's support for direct connections from one user to another was extremely compelling. This was the VoIP protocol which would lead to a complete revolution in communications... more»
The Tyee, an independent on-line magazine based in BC wrote a story about net neutrality more than a year ago, noting that most Canadians are sleeping through the debate. They followed up again last week. Despite what is called a "perfect storm of events that may crystallize the issue for consumers, businesses, politicians, and regulators," there hasn't been an overwhelming outcry, despite extensive press coverage of the most recent network activities. There are a number of voices who present a conspiracy theory on traffic shaping in Canada... more»
The internet is a shared resource. Different access providers begin mixing traffic at different places, but sooner or later, my internet gets mixed into yours. The Canadian Association of Internet Providers (CAIP) application to the Canadian Radio-television and
Telecommunications Commission (CRTC) seems to acknowledge this shared nature with its reference (at paragraph 50 of its application) to the description of the Gateway Access Service its members resell, a description complete with a graphic of a cloud -- a sign that the resource is being shared... more»
The Wall Street Journal today reported that FCC Chairman Kevin Martin wants to reject a Petition for Declaratory Ruling filed by Skype that would establish a wireless Carterfone policy, i.e., that wireless carriers must allow subscribers to use any compatible handset to access any application, content or software. Chairman Martin has confidence that the marketplace solutions obviate any necessary FCC intervention. Such optimism must derive in part from the apparently newfound willingness of one major wireless carrier, Verizon, to support aspects of open access. Perhaps Chairman Martin has confidence in the marketplace based on the magnanimous offer of most wireless carriers to pro-rate their early termination penalties by $5 a month. But here's the rub... more»
