VoIP Bandwidth Calculator

I recently ran into a cable TV executive who reported some issues with a recent business hosted IP telephony installation. The issue was the sizing of the upstream bandwidth. Apparently, the issue was that the hosted IP telephony system also was interacting with some premises gear that essentially required four call paths to set up a session.

Here's a table to estimate the bandwidth required to support a given number of lines (voice paths) across a broadband connection, using a variety of codecs, and assuming you do not have the aforementioned problem.

Will Apple’s Subscription Plan Drive Developers to Android?

Google and Apple are in a building race for the loyalties of content providers and developers using their respective application stores.

While the iPhone has the largest app store, Google recently overtook Nokia and other phone manufacturers with the largest mobile operating system market share.

Google's "One Pass" will allow publishers to sell subscriptions with better terms than they can get with Apple. Google is only taking a 10 pecent share of the revenues, will Apple takes 30 percent.

Why is NCR Renting DVDs?

You might have seen Blockbuster DVD rental kiosks in grocery stores. Those kiosks actually are owned by NCR. You might wonder why NCR is in that business. Basically, NCR is doing so as a way of increasing demand for its automated terminals, and to gain operating knowledge that could be helpful as NCR attempts to create new uses for automated terminals.

Today NCR makes most of its money from automated teller machines and retail checkout systems. Nobody knows yet how much more that might change in the future, but observers might point to substantial use of retail kiosks in Japan, for example, as pointing to the possibility that consumers might want to buy a broader array of products from kiosks in the future.

How Airlines Use Twitter

Social media is a two-edged sword, a tool brands can use, but also a tool consumers can use. Note that United Continental gets 57 percent negative tweets.

It's tough to control a brand message when that level of negative commentary is being posted.

France Could Outlaw Skype

Many executives in the telecommunications industry, a decade ago, thought it was unfair that VoIP services such as Skype did not have to abide by many of the rules that govern providers of public telecommunications service. Contributions to universal service funds and payment of taxes were sticking points.

Skype is not "registered" as a "telecommunications provider" in France. Skype also has been the subject of legal proceedings in France for that reason. So it appears the issues will be raised again.

Readability Tests Apple App Store In-App Fee Policy, Loses

Readability is a software development boutique whose reading functionality is part of the Apple Safari browser, but whose Apple App Store app (Readability iOS ) has been rejected, apparently because the app uses a non-Apple in-app purchase mechanism.

Readability says content providers get 70 percent of revenues when users buy content, but that Apple's 30-percent fee for app content sales then destroys the business model.

Which brings up an interesting question: as cloud-based software subscriptions start to proliferate, will Apple apply the same 30-percent fee? And, if so, will providers of all sorts of cloud-based apps avoid the App Store?

There are signs Apple already has thought about this, and does not plan to impose the same arrangements for cloud-based software apps. See http://www.macrumors.com/2011/02/21/steve-jobs-email-suggests-in-app-subscriptions-dont-apply-to-software-as-a-service/

Mobiles are Most-Owned Gadget

Mobile phones are by far the most popular device among American adults, especially for adults under the age of 65. Some 85 percent of adults own cell phones overall. Taking pictures (done by 76 percent of cell owners) and text messaging (done by 72 percent of cell owners) are the two non-voice functions that are widely popular among all cell phone users.

Desktop computers are most popular with adults ages 35-65, with 69 percent of Millennials, 65 percent of "Younger Boomers" and 64 percent of "Older Boomers" owning these devices.

Millennials are the only generation that is more likely to own a laptop computer or netbook than a desktop: 70 percent own a laptop, compared with 57 percent who own a desktop.

While almost half of all adults own an mp3 player like an iPod, this device is by far the most popular with Millennials, the youngest generation. Some 74 percent of adults ages 18 to 34 own an mp3 player, compared with 56 percent of the next oldest generation, Gen X (roughly between the ages of 33 or 35 up to 43 or 46).

Game consoles are significantly more popular with adults ages 18 to 46, with 63% owning these devices.

Some five percent of all adults own an e-book reader.

Amazon Says Kindle Beats iPad

The thing about investment bubbles is that the irrational exuberance occurs because there is a genuine sense that big things are possible. Since 2010, there has been some sense that an Internet bubble is forming, that expectations are unrealistic. Of course, that is the excessive side of the belief that something big is afoot. We probably have both at the moment: a time when some truly new and big things are coming, and the near certainty that valuations are too rich and that too many firms will be funded.

Teens Text Because it is Faster than Voice, Also More Fun

It would come as no surprise that teens and many younger users have a preference for texting rather than calling. In 2010 a Nielsen survey suggested that the overwhelming reason SMS resonates with teens is that it is easier than making voice calls.

About 22 percent of teens surveyed said texting was easier than making a call, while 20 percent said it also was faster than making a voice call. Voice activity has decreased 14 percent among teens, who average 646 minutes talking on the phone per month.

While voice consumption rises and peaks at age 24, only adults over 55 talk less than teens. Teen females, who are more social with their phones, average about 753 minutes per month, while males use around 525 minutes.

In 2009, teens texted instead of calling because it was fun. They still think it is fun. But beyond that, it also seems to be seen as a better way to communicate.

Calling from Inside Gmail

Since the third quarter of 2010, users have been able to launch voice calls using Google Voice from inside their Gmail accounts, and at this point, calls to destinations in Canada and the United States are free. Separately, Google has created a Google Voice iPhone app, while other firms obviously have created their own mobile apps for "over the top" calling.

Developments such as these are examples of voice becoming a feature embedded in applications, as well as voice becoming a "mobile app" and a "browser app," as many proponents of "voice 2.0" have suggested would increasingly become the case.

Apple iPhone Cartoon Lampoons HTC Evo

Warning: this is funny, but there are several "F bombs." Also, despite the cartoon, I vastly prefer, and use, the HTC Evo, not the Apple iPhone, though there are six active iPhones in the immediate family (100 percent of my children and their "significant others.")
