Broadcast lectures on cell phones

Many universities are now setting up to broadcast lectures over their LANs, often in video. Many students simply watch from their rooms, or even watch later. There are many downsides to this (fewer show up in class) but the movement is growing.

Topic: 

Patient's room phone with basic presence

Those who know about my phone startup Voxable will know I have far more ambitious goals regarding presence and telephony, but during my recent hospital stay, I thought of a simple subset idea that could make hospital phone systems much better for the patient, namely a way to easily specifiy whether it's a good time to call the patient or not. Something as simple as a toggle switch on the phone, or with standard phones, a couple of magic extensions they can dial to set whether it's good or not.

Capacitive touch sensor on outside of cell phone

Since writing in the previous post about an end to all ringing of cellphones through the use of cheap bluetooth enabled vibrating devices in watches, belts, shoes and other wearables, I've been listening to the cacophany of rings in public meetings (even those were people are told to put their phone on vibrate.) One thing I am sure we've all experienced is hearing somebody's ring get louder and louder in a meeting as they fumble to get the phone and open it to press the silence button.

Topic: 

End ringtones -- bluetooth "personal vibrator" watch.

No, not the sexual kind of personal vibrator. Today we regularly hear reminders to put phones on vibrate, and they are often ignored. The world is becoming rapidly swamped with loud, deliberately destracting cell phone ringtones. (The ringtones themselves are a business.)

Why isn't my cell phone a bluetooth GPS

GPS receivers with bluetooth are growing in popularity, and it makes sense. I want my digital camera to have bluetooth as well so it can record where each picture is taken.

But as I was drivng from the airport last night, I realized that my cell phone has location awareness in it (for dialing 911 and location aware apps) and my laptop has bluetooth in it, and mapping software if connected to a GPS -- so why couldn't my cell phone be talking to my laptop to give it my location for the mapping software? Or ideed, why won't it tell a digital camera that info as well?

Wiretaps beget wiretaps -- I don't hate that much to say I told you so.

For some time in my talks on CALEA and VoIP I've pointed out that because the U.S. government is mandating a wiretap backdoor into all telephony equipment, the vendors putting in these backdoors to sell to the U.S. market, and then selling the same backdoors all over the world. Even if you trust the USGov not to run around randomly wiretapping people without warrants, since that would never happen, there are a lot of governments and phone companies in other countries who can't be trusted but whom we're enabling.

Let's see neighbourhood fiber lan

The phone companies failed at the fiber to the curb promise in most of the USA and many other places. (I have had fiber to the curb at my house since 1992 but all it provides is Comcast cable.)

Commercial I would like to see

Tom Selleck narrates:

Have you ever arranged a wiretap in Las Vegas without leaving your office in Fort Meade?

Or listened in on a mother tucking in her baby from a phone booth, all without the bother of a warrant?

Or data mined the call records of millions of Americans with no oversight?

You will.

And the company that will bring it to you... AT&T

EFF sues AT&T for giving access to your data without warrants

A big announcement today from those of us at the EFF regarding the NSA illegal wiretap scandal. We have filed a class-action lawsuit against AT&T because we have reason to believe they have provided the NSA and possibly other agencies with access to not only their lines but also their "Daytona" database, which contains the call and internet records of AT&T customers, and probably the customers of other carriers who outsource database services to Daytona.

MP3 Podcast of my talk at Emerging Telephony on how to love CALEA

Last week I spoke at O'Reilly's Emerging Telephony (ETEL) conference about CALEA and other telecom regulations that are coming to VoIP. CALEA is a law requiring telecom equipment to have digital wiretap hooks, so police (with a warrant, in theory) can come and request a user's audio streams. It's their attempt to bring alligator clips into the digital world.

Curses on you, bluetooth

Well, I am going to get a bluetooth cell phone shortly and so I got a headset and dongle to use on my laptop, where I also make VoIP calls.

I was shocked, flabbergasted to find that the bluetooth headset profile only transmits audio at telephone quality 8khz sampling rate. So even plugged into my laptop for hifi (didn't think I
would ever need to use that term again) recording, it sounds like a telephone, and likewise for
playback.

Why? Why? Why?

Reinventing the phone call -- demos for team members for re-startup this week

This week I will be doing some demos of Voxable, my system that combines VoIP, presence and all sorts of cool stuff I won't be writing about in the public blog to create a new user interface for the phone that is both as modern and internet as it can get while also being a reflection of the ancient interface for the phone that was lost.

Smarter headsets, smarter headset jacks

Millions now use PCs for VoIP and online audio chat, and you soon realize the quality is vastly better if everybody uses a headset.

But there's a problem on PCs. If you plug in headphones, it usually disables the regular speakers, often in hardware. So if you leave a headset connected, the system can't play a ring sound when somebody calls you.

Free incoming vs. pools of cellular minutes

As noted, in Australia, I picked up a SIM at the airport for my unlocked phone. Australia, like Europe and most other places outside North America, uses a system where incoming calls to cell phones are paid by the caller, and are free to the mobile owner. As you may know, in North America and a small number of other countries, the mobile owner pays for airtime on incoming calls, and they look like ordinary landline calls to the caller.

Button on cell phone to answer and play pre-recorded message

Of course, if you don't answer your cell phone it goes to voice mail and plays your pre-recorded message.

But what we need are phones which can answer and play a pre-recorded message for a short time. In particular a message of the form, "Hold on, I'm in a meeting and must keep silent. However, I'm walking out of the meeting right now while you hear this recording, and in a few seconds I'll be able to talk to you. Hold on... Still walking..."

End the Universal Service Fund

Recently I attended a panel that covered, among other things the universal service fund. This fund, which you usually see as an add-on on your phone bill, taxes urban phone users (through their interstate carriers) to subsidize local phone service for the poor, the rural, schools and health care. Sounds noble, but it collected over 5 billion dollars in 2002, and now the question has come about how to apply it to the internet now that people are making phone calls over the internet.

Topic: 

Mesh network of cell phones when the towers go down

Klein Gilhousen, one of the founders of Qualcomm, proposed this evening at Gilder's Telecosm that cell phones be modified, if an emergency shuts down the towers, to do some basic mesh networking, not so much for voice, but for text messaging and perhaps pust-to-talk voice packets, as well as location information from their internal GPS if present.

Why the high price for Skype

The reason that eBay paid such a huge price for Skype has now become clear. There were several companies competing to buy Skype, and just before the bidding closed, eBay decided the best way to win was to place a giant bid just a few seconds before the end. (This might be known as bid skyping.)

A change in the demographics of your life due to IM

When I left high school, I didn't look back. I have a few friends from HS, but mostly I found many more like minded people in university. That seems to be a male trait, in that more women seem to keep a circle of friends from HS than men do, but for those that find themselves at university, this is where the social circle that may stay with us our entire lives is formed.

Topic: 

The phone number is dead

Here at the VON conference, there's lots of talk about numbering. While SIP had a dream of calling people using an E-mail address, the market has delivered devices with numeric keypads only, particularly in the mobile space. So nobody uses SIP URLs or domain names of any kind, and everybody worries about mapping to and from numbers. (Another thing Skype mostly ignored.) The regulators try to regulate VoIP by claiming they have the power when it makes calls to and from the legacy PSTN with its numbers.
