That sounds a bit confusing, but the feature is straightforward in practice. After installing the app on your phone, you’ll be asked to authenticate using Facebook Connect. You’ll then be able to see a list of all of your Facebook friends who are currently logged into Facebook Chat. Tap the one you wish to call, and they’ll receive an instant message with a link inviting them to join a free voice call with you. If they click it, a website will pop up and they’ll be able to talk using their computer’s speakers and microphone (they don’t need a Jajah account). The whole process, which you can see in the video below, takes about 10 seconds.

And in case you’re worried about privacy, the service masks your outgoing phone number. The company originally launched this feature last fall in the UK with support for its Blackberry app, but for some reason it’s remained in private beta. The Android app is now live for everyone, and the iPhone app will be released pending Apple’s approval (the Blackberry app is still on the roadmap, though the release date sounds less soon).

Jajah isn’t the only service that adds voice calling functionality to Facebook — last October Skype released Skype 5, which lets users call their Facebook friends’ phones (instead of sending them a link and initiating a call in the browser). Rumors continue to swirl that Facebook is working with Skype to bring deeper integration of video calling to the social network.

After selling his latest company, Jajah, to Telefonica for $207 million a year ago, co-founder Daniel Mattes has set his sights on the electronic payments market.

Mattes, who has apparently been baptized the “Bill Gates of the Alps”, has started a new company called Jumio.

Not much is known about the company to date, and this is its vague pitch on the website:

“You buy. You sell. And Jumio is making everything in between a lot easier.”

Tom Foremski met with Mattes earlier this year and believes Jumio will become one of the hottest startups of 2011.

According to Foremski, Mattes has figured out a way to make secure digital payments that cannot be hacked. Mattes said he discovered a patent filed by two engineers based in Israel and acquired it for several hundred thousand dollars:

This technology will make it possible to provide payments services at a far lower rate than the credit card companies because the risk of fraud has been removed. Jumio is currently working on the infrastructure for the payments system but it will also license its technology to large retailers such as Amazon to run on their platform.

He won’t yet say how he can guarantee that his payments systems cannot be defrauded — but I’m looking forward to finding out.

And now Mattes has tapped a friend of his, Bosnian opera singer Jasmin Bašić, to tease us a little more by having the tenor sing the Christmas classic ‘Silent Night’ with custom lyrics.

Enjoy and happy holidays.

This is interesting for a few reasons. First, it’s obviously a fairly speedy integration given the size of O2. Jajah CEO Trevor Healy also says that this marks the first time that a global carrier is offering a VoIP-powered service to its subscribers — he explains that O2 is willing to embrace the ‘Silicon Valley approach’ to digital communications, as opposed to holding steadfast to tradional voice services. Here’s to hoping the US carriers follow suit.

O2 says it will be rolling out further Jajah-powered features in the next few months (presumably including a rollout of Global Friends to countries outside of Germany). O2 has 54 million subscribers across Europe.

The reports from a few days ago that the Jajah deal with O2 closed at $200 million were correct. Telefónica Europe (aka O2) just announced that it bought Jajah for 145 million Euros ($207 million) in an all-cash deal.

Jajah, which provides Internet calling services and thus competes with Skype, was on the block since at least November (which TechCrunch was first to report on), following Google’s purchase of much-smaller Gizmo5.

Jajah has 15 million subscribers and has served up more than 1 billion VoIP calls.

Jajah will continue to operate under its own brand. The sale was not a happy affair for everyone involved, however. The deal was largely driven by Jajah’s investors, particularly Sequoia. We hear CTO Amichay Oren has left the company because he and his engineering team in Israel didn’t get treated the same as their counterparts in the U.S. In these types of deals, not everyone ends up winning. Jajah turned out not to be the next $1 billion company in Sequoia’s portfolio.

Given the fact that it raised $33 million in total capital, a $200 million exit is a decent outcome.

It was believed that Microsoft and Cisco were two other companies that were vying to get the company. Back in June, the company served up its 1 billionth VoIP call. While the company has some 15 million subscribers of its own, many of the calls originate from Yahoo Messenger, which has used Jajah since 2008 for its VoIP calls. They also have a deal in place with Microsoft.

The company has raised over $30 million in funding over four rounds. They are backed by the likes of Sequoia and Intel Capital. O2 is the mobile arm of Telefónica Europe, and had been considered the company with only an outside shot at theacquisition, especially considering Microsoft’s partnership with Jajah. Earlier reports indicated the price could be driven as high as $400 million in a bidding war, instead it appears to have stayed on the low side.

We’ve reached out to Jajah for comment on the matter, and will update when we hear back.

Details are scarce at the moment, but Microsoft, Cisco Systems and Telefónica Europe (O2) are said to be looking to buy the venture capital-backed company for a price ranging from $200M to $400M. We’re digging for more information.

Jajah was founded back in 2005 and in March 2006 introduced the world to a pretty decent consumer service that allowed cellphone users access Jajah’s low-cost calling system through their mobile devices, over the Web. Jajah went on to raise $28 million in VC funding from investors like Sequoia Capital, Globespan Capital Partners, Deutsche Telekom and Intel.

The Skype rival amassed about 10 million users when in April 2008 they announced a deal that would bring its premium voice services to nearly 100 million Yahoo Messenger users more. The deal proved crucial for Jajah, which connected its 1 billionth call last Summer. And that was before it turned to Twitter to spread the voice service even more.

Jajah says it currently serves over 25 million consumers and business callers in more than 122 countries, and provides calling access to more than 200 destinations globally. It’s unclear how much revenue it is generating from these users, but it’s apparently enough – or has enough potential to scale and grow – to make for an interesting strategical acquisition target for companies with deep enough pockets to engage in a bidding war.

It’s odd to see O2 mentioned as one of the companies who’s sitting at the negotiation tables, and I consider Microsoft and Cisco to be more likely buyers. Both of them sit on heaps of cash and are undeniably acquisition-hungry, and Redmond has the added benefit of having entered into a partnership with Jajah on enterprise IP communication solutions.

The price range seems to be on the high end, but that’s what happens when a bidding war goes the way the company that’s on the table (and its financial backers) would want it to go.

We’re cataloging this as a solid, plausible rumor for now and will update with more information / confirmation as soon as it comes in.

Starting today, Jajah is rolling out a brand spankin’ new service – Jajah@call, a Twitter user-to-user phone call solution. That’s right, ladies and gents. Jajah, the self-proclaimed “world’s most innovative IP communications company,” is bringing this new feature to the wildly popular microblogging service.

This is not too much of a surprise, really, in light of Facebook’s recent voice feature announcement – these are all communication tools, after all, and what is the pinnacle of communication if not voice? It will provide Jajah with increased exposure, while giving always connected Tweeters a new “built-in” VoIP tool. See kids, healthy competition is a good thing!

According to the press release:

How does it work?

To make a call simply send a Twitter message (tweet) with “@call @username” where the ‘username’ is the Twitter name of the person you wish to call. If that person follows you on Twitter, a free two-minute call — the verbal equivalent of a tweet — will be initiated. Both Twitter users need to be JAJAH users as well.

JAJAH@call works no matter how you use Twitter, whether it’s on a computer or mobile phone, at Twitter directly or using a Twitter-client such as Seesmic (web and desktop), TwitterBerry (BlackBerry), Tweetie and Twitterfon (iPhone), and Twidroid (Android).

[Editor's Note: Ha! A 2 minute voice call is the verbal equivalent of a tweet? The verbal equivalent of one of my tweets is 20 seconds of Sims-esque babbling with the occasional semi-coherent rant about whatever coffee shop I'm at. -Greg]

I’m not sure how necessary or useful this new feature is, but then again I’m not much of a twhore. The good news is that users are not required to reveal their phone number (i.e. it can be kept private) as they just need to know the other person’s Twitter handle and, like any phone service, you can simply choose to ignore a call. It’s also really nice that the service works via users’ mobile devices, and is not limited to more traditional computing devices.

On the downside, not only does @call require both participants to have Twitter accounts (duh), it will only work if each person also has an existing Jajah account (meh). That really makes the whole thing a lot less desirable; yet another account/login to remember.

In any case, has anyone had a chance to try this out yet? Let us know! Talk to you #later.

The new feature offers a good middle ground between the text interactions you typically go through on dating sites and actually meeting your potential match face to face. The integrated Jajah widget will allow you to talk with a prospective match though an online voice call, without having to divulge any of your real contact information should things turn messy.

Voice chat is a premium feature on both eHarmony and Match.com, going for around $5/month. Jajah declined to share any details regarding the revenue split between the dating sites and the VoIP service, but it sounds like the company is going to be generating quite a bit of money from the deal, especially given the negligible costs associated with actually connecting the calls.

This isn’t the first time dating services have implemented voice chat — Match.com previously offered its own service that was powered by the now-defunct Jangl, but it’s been out of action for the last nine months. This is the first time eHarmony is implementing a similar service.

JAJAH CEO Trevor Healy says the service has attracted 25 million users since its launch, which means every user has on average made 40 calls through the company’s IP telephony platform if we use back-of-the-envelope calculations. By comparison, rival Skype boasts over 405 million registered users globally and in a recent press release claimed people have made more than 100 billion minutes worth of free Skype-to-Skype calls alone. Other competitors include Jaxtr, Truphone and Nimbuzz.

If you’re interested: the 1 billionth call was attributed to San Francisco resident Ila Vasudev Zeff, a 29 year-old woman who was calling her mother in India.

Jajah, a popular VoIP service provider, has released a new English/Chinese translation service called JAJAH.Babel just in time for the Olympic Games. The service, which was developed in conjunction with IBM, allows users to call a free number to get a near-instant translation of spoken sentences. The service isn’t meant for voice calls abroad – instead, it’s a handheld translator. After speaking your message into the phone, you hand it to the person you’re speaking with, and the phone spits out the translated message.

Using the service is fairly simple, and should work from any phone line:

How does JAJAH.Babel work? From English to Chinese or in reverse:
Dial JAJAH.Babel from any phone. U.S. local access number: +1.718.513.2969
Choose which language you want your message translated into (either English to Chinese or Chinese to English)
Say your message and press #
You will be able to confirm that your message was properly understood by the system.
The message will automatically be played back in Chinese. If you wish, simply hand your phone to the other person or put the phone on loudspeaker so they hear the message.
The other person can then record a message in Chinese, following the steps above, and you will hear their message in English.

To help test the service I recruited TechCrunch intern Matthew Schulz, who is fluent in Chinese. His conclusion was that it worked surprisingly well. The translation from English to Chinese sounded a little bit awkward, but the meaning was obvious. As for speech detection, the service had some trouble when he spoke Chinese in his normal tone, but when he enunciated a bit more than usual the results were almost perfect.

For now, the service is limited to translations between English and Chinese Mandarin, but the companies plan to release new languages in the near future. You can get more information about the service along with more local access numbers here.

Just over a week ago the founders of and five engineers from VoIP services provider Jangl left for Jajah after the company failed to find a proper suitor. Following their departure, it was unclear what would happen to Jangl’s assets and remaining staff. Now we hear from multiple sources close to the deal that Live Universe has agreed to acquire both.

This appears to conclude the Jangl saga that started late last fall. Around that time, Jangl’s board began telling the founders to pursue an acquisition strategy in lieu of raising more money. The board’s decision came even when the company had closed deals (some profitable) with several partners, including Plentyoffish and Tagged.

We hear there was a disconnect between the VCs, who had a more enterprise background, and Jangl’s executives, who were set on developing a consumer-facing brand. The founders, and Michael Cerda in particular, are said to have worked diligently to carry out the board’s marching orders. But despite many companies showing interest in Jangl, it struggled to find the right company for its exit.

An acquisition deal (apparently with WhitePages.com) came close but unraveled after the terms changed and became far less acceptable. With no apparent options left, much of the company’s staff was notified that they would probably have to find new work, and it was finally announced that Jangl’s founders were indeed jumping ship.

Just what Live Universe plans to do with everything they left behind has yet to be seen. I’m sure Jangl’s partners will be interested in hearing the fate of their agreements, if they haven’t already.

Under the deal, JAJAH will provide its proprietary telephony infrastructure, payment processing, and customer care to Yahoo Messenger users using the platform for receiving calls from the PSTN network, or for making calls to land lines and mobile phones.

The announcement coincides with JAJAH moving into new territory as an indirect to consumer provider as well as its direct to market service. Yahoo is the first major U.S. technology customer/partner of JAJAH’s Managed Services and JAJAH told TechCrunch that they expect to announce new partners including landline operators, cable companies and mobile carriers in the coming weeks.

JAJAH’s existing VOIP service recently passed the 10 million user mark.

Still, you are really asking to be distracted if you turn this feature on. Or disappointed. What if you put the badge on your site and no one wants to chat?

In contrast to their competitor, Jaxtr, they’ve been mainly spreading through a series of direct deals with social networking sites (Match.com, Tagged, AdultFriendFinder, and Fubar) and a Facebook/Bebo application (potentially on 80 million profiles). Jaxtr, on the other hand, has been spreading mainly through email links and personal websites (5 million users in under 5 months).

Now they’ve forged a deal to be featured on the maverick of dating sites, PlentyOfFish. PlentyOfFish is like every other dating site you’ve heard of, but free. Free has actually paid off pretty well for founder Markus Frind, who runs the site from his Vancouver apartment and takes in over $10 million a year in advertising.

Comscore ranked the site the number one dating site in December 2007, with an average of 1.3 billion page views a month (70,000 sessions and 3 million page views an hour).

Jangl’s widget will let daters call each other, send SMSs, and leave voice mails all without sharing a real number. The functionality makes it easy to take the next step in a relationship without sacrificing privacy, or just discreet phone sex. Calls will be terminated on Jajah’s servers as part of their existing relationship. Like PlentyOfFish itself, Jangl will be monetizing the service through text advertising; a first for the company. On other sites, the service is either ad-free or paid for as part of membership (match.com).

I’ve found social calling widgets (particularly Jaxtr and Jangl) to be the most attractive part of the VOIP market because they’re not competing in a race to the lowest calling rates, but adding real utility to our existing phone lines. Other voice widgets include Ccube, Tringme, and Snapvine. While monetization is still somewhat up in the air, both companies are testing out business models (paid Jaxtr minutes, or Jangl’s revenue sharing). Going forward we’ll see which models do and don’t work. I also expect both companies to continue adopting more advanced features similar to Google’s GrandCentral.

In August, Jaxtr reported 1 million users and $10 million in financing. In response to the growth, they’ve brought on Taneli Otala as VP of engineering, the former CTO of MySQL.

It’s hard to compare these new numbers with Jaxtr’s main competition, newly partnered Jangl and Jajah, because Jangl has only reported numbers about their potential reach. These numbers highlight deals with websites such as Match.com or Tagged (which reaches 40 million profiles). Jajah recently crossed over 2 million users.

Jaxtr offers a really comprehensive calling system. It lets people call you anonymously online through a widget or unique Jaxtr phone number that connects to your real number. Similar to Jangl, Jaxtr adds a host of advanced features such as call screening and voicemail, all without giving away your original phone number. They’ve also built out more functionality similar to GrandCentral. Users can link multiple phones to their account, and forward certain phone numbers directly to voicemail.

Jaxtr CEO Konstantin Guericke says about 85% of their users are international, with the other 15% based in North America. This makes sense because one of most direct benefits of VOIP systems like Jaxtr is the long distance cost savings to over 220 countries. VOIP calls save money on long distance calling by connecting calls over internet lines instead of more expensive standard phone lines.

Jaxtr users have 100 free minutes to use per month, however calls to other Jaxtr users don’t use these minutes. Jaxtr plans on monetizing by letting users buy more minutes and running advertising on the web pages of free accounts in the future.

The deal makes a lot of sense. Jajah is a high-profile VOIP startup making great strides in bringing VOIP to regular telephony (with over 2 million registered users), but their recently launched click-to-call widget hasn’t yet given them a large web presence. Jangl’s calling widget, however, has distribution on over 40 million user profiles through deals with social networks like Tagged.

Specifically Jangl will be using Jajah’s back-end VOIP engine to serve their calls. With Jajah in over 122 countries, it will give them a much greater reach than previously. In turn, Jangl will be using Jajah’s newly launched pre-call advertising engine to monetize their service with geographically specified ads powered by Oridian (another one of Jajah’s recent partnerships). The two are also alluding to future “strategic development and emerging products” as well, but not saying much else.

If the two ever decide to merge (not that we have any indication that they will), either one would only have to change the last three letters of their name (preferably Jajah—Jangl is the better name, at least for English speakers). Some customers might not even notice the switch.

Jajah is teaming up with advertising network Oridian to let users pay for minutes by listening to targeted advertisements. It’s an opt-in system where users hear and see very targeted advertising content and receive credit in their JAJAH accounts for each message. Ads are targeted based on the phone’s location. For example, “If you own a furniture store that you want to introduce to your local community, your messages will be played to your prospective customers next door”, as founder Roman Scharf explains. The messages will play above the ring tone right before the call starts similar to the example embedded below.

Since Oridian is an international ad network that helps US sites monetize international traffic, I can’t imagine they’ll be focusing on your cross town calls, but rather the long distance international ones a VOIP provider effectively delivers for local calling rates (you still have to pay for minutes from your telco). Jajah says these ads will allow users to earn back their entire phone bill, or even make money too.

To make money back, you’ll have to listen to ads worth more than Jajah’s calling charges. Virgin’s Sugar Mama ad supported option lets users earn a minute for each minute of advertising heard. Jajah’s VOIP network has a significantly lower cost base costing at most three to four cents per minute to users on long distance calls. This makes it more feasible to support through advertising compared to standard phone time earned on Virgin, which may not make them money, but provide an effective rebate for price sensitive users willing to work for it.

Nearly every VOIP related startup has their own click-to-call widget, Jajah, Jangl, Jaxtr, and even GrandCentral. These widgets let you easily and sometimes anonymously set up a call with friends over the web. They’re very useful and come packed with features like voicemail and texting. However, each of these services connects phones to phones, which still eats away at your mobile minutes while you’re talking to that business contact or MySpace hottie.

http://www.tringme.com/tringme.swf?uid=1&username=TringMeTringMe offers a bit more flexibility. Callers can ditch their phone and call directly through their Flash widget to your mobile phone, landline, and GTalk (Yahoo and Skype coming soon). All they need is a microphone and one click. Although they’re still in private beta, you can try the demo widget to the right for an idea of the experience.

Similar to the other services, your phone number is kept private and the calls are free (now’s the time for that overseas call). You can also set the widget to just receive voicemails, which are emailed to you, saved on your standard mailbox, or recorded and played back in GTalk. There is one major drawback, though. Since there is no virtual phone number involved, callers have to be at a computer and can’t call you while they’re on the go.

Naturally such an easy and anonymous calling service is susceptible to abuse, and I don’t see any countermeasures in place to keep out prank calls and telemarketers. The other services have verified phone numbers and white/black lists to keep abuse to a minimum. I expect TringMe will have to incorporate similar controls to make people more comfortable with using the widget.

The call buttons are available to registered Jajah users and come as a bit of embed code you can put on your web page or at the end of an email. They come with several customizations. You can adjust the CSS styling, adjust the number it calls, and restrict which countries can try to call you.

When users click the button, the caller enters their phone number and Jajah connects the two parties over a VOIP line. The callee is then told who called and asked if they want to accept the call, say they’re busy, or blacklist the number. If they accept the call, the minutes are charged to their Jajah account, like an “800 number”. At two to three cents per minute, it can be used for some cheap long distance calling. For the cost conscious, Jaxtr and Jangl are still free, however.

All of them allow users to call normal, non-VOIP telephones at greatly reduced costs. These savings can be captured whether or not the parties to a phone conversation are using VOIP-enabled phones, since transmissions can jump from PSTN to VOIP and vice-versa at certain junctions. For example, a cellular call to your buddy across the country might start on PSTN, quickly jump to VOIP for long distance travel, and jump back to PSTN near its destination.

The key is to use VOIP to strip out some or most of the cost of the call, allowing these startups to offer very low cost calling to consumers. These aren’t free calls, though – any time a normal phone line is used for at least part of the call, particularly the termination, the teleco’s get a toll.

Making sense of all of the new VOIP startups is daunting, so we’re categorizing them by use cases. For a comparison of features, prices, and more companies, check out this chart.

I’m Cheap and I Have a Computer

By far the cheapest way to go with calling is to get a desktop client. VoIP clients on your desktop allow users to make calls from one computer to another across the VoIP network. For an added fee, you can connect to a standard phone on the PSTN phone network for calls to or from your computer. Most of you will know this as Skype-in and Skype-out.

The most well known desktop client has been Skype, with over 100 million users. The big guys – Yahoo, Microsoft, and Google – also have their own VoIP desktop clients. Since the VoIP offerings have been built into their IM clients, combined they comprise a potential market of over 340 million subscribers.

A younger startup, the Gizmo Project, launched in July of last year. They have a reported 2 million downloads of their application. The application functions like Skype, supporting IM and VoIP calls. The Gizmo Project has the unique distinction of not only offering IM and VoIP calls, but also free calls to the standard phone network if you promote their product to a friend and stay an “active user“.

Hullo and Nimbuzz are other desktop VOIP application we’ve covered.

I like WiFi and Saving Money

If the idea of holding a laptop up to your ear to talk to your friends doesn’t sound appealing, Nokia’s WiFi phones may be for you. The Nokia N800 is a great example and takes advantage of the free in network calling of the desktop applications. Fring, which gives Skype-like functionality over 3G/GPRS and WiFi, is very Nokia friendly and just moved on to Windows Mobile. However, you still need to pay for calling standard phone lines and buy a real phone number so your friends on those dated PSTN phones can call you back. They recently raised another round of $12 million and have received a lot of praise from us in the past.

I Have a Social Life WiFi Can’t Contain

If you’re not in WiFi heaven (Mountain View) or perpetually hanging out at WiFi hotspots, there are some other semi VoIP solutions that can still save you some money, at least on long distance calls. Mobile VoIP providers don’t throw out the PSTN lines, but instead save customers money by bridging the connection between two calls the caller and callee make to local numbers with cheaper VoIP lines. However, these solutions work best for long distance where bridging local calls makes sense and still cost minutes on you mobile plan. The main advantage is that it works on that hot new phone you picked up after reading a CrunchGear review.

There are quite a few players in this category, including desktop VOIP client Skype’s own player, iSkoot. iSkoot is the mobile version of Skype, which allows you to place calls to your Skype contacts by calling their Skype servers to route the calls. Shape Services recently hacked together an iPhone version of Skype, but reports are that is suffers from AT&T’s low transfer rates. Another startup, EQO was competing in that category until they stepped out on their own with a VOIP, IM, and messaging mobile application that we’ve written about earlier.

The biggest kids on the block, with $28 million and $24.5 million in financing respectively, are Jajah and Truphone. The two startups allow you to easily make calls from your mobile phones. However, Jajah uses VOIP to bridge two standard phone lines, while Truphone can make truly free calls if your phone has a fast enough data connection. Their relationship has been further complicated with T-Mobile, a Jajah investor, kicking Truphone off their network. T-Mobile made their own venture into WiFi calling with “Hot Spot at Home“, which lets you add unlimited calling from your WiFi network for $9.95 extra a month.

Who’s Winning

While Skype is apparently making money for eBay, no other startups are profitable as far as we know. But the communications industry itself is hurting. There’s a shift is afoot particularly in the mobile industry as voice revenues drop from $51 a month in 2000 to $43 a month last year, carriers are looking for a ways to set themselves apart in the $118 billion U.S. cell-phone market. Data plans are widely heralded as the future for increasing telco annual revenue per user (ARPU).

However, this doesn’t mean an easy path for VOIP. VOIP on your mobile phone is facing quite a few challenges. The most basic problem is just distributing your application on the plethora of mobile platforms. Mobile carriers aren’t helping because they’re still reluctant to hasten the demise of their voice and content services. Verizon and their variety of subscription services (VCast, maps) are perfect example of the latter.

We’ve expressed a lot of dissatisfaction over the usability of a lot of these applications too. After it’s on your phone, VOIP services can add another rats nest of differing call rates and can sometimes only save you money on long distance calls while still costing minutes. With national long distance included in a lot of U.S cell plans, it may not make sense for a lot of users. Even still, that leaves dozens of VOIP carriers (just check our chart) competing to push down calling rates.

Then there’s the bandwidth requirements. Mobile data networks are generally not fast enough to ensure a high enough quality of service. The best way to deliver VOIP, over WiFi, still isn’t everywhere, no matter how hard Google tries. 3G provides better coverage and sufficient bandwidth, but is still controlled by carriers, who can throttle the upstream bandwidth to affect VOIP’s quality. Verizon reportedly plans to offer VOIP over 3G, but hasn’t come through on the promise since 2005.

Consequently, VOIP remains fragmented across the landline, desktop, and mobile platforms.

The crux of the matter is that winners in the this category will have to play nice with the carriers. Even startups that work purely off of data plans or your desktop need the carriers to provide the mobile networking infrastructure. Jajah is in the best position to work with carriers, by offering cheaper long distance calling while still using calling minutes that are carriers bread and butter. Services that operate over data networks, like Fring and the Gizmo Project may offer consumers better deals by circumventing the carrier’s voice plans over increasingly speedier data networks, but are directly competitive with the carriers. Undercutting the profits of these incumbents will eventually cause them to butt heads as TruPhone did with T-Mobile or some carriers have by disabling VOIP on N95s. Short of these startups changing their revolutionary rhetoric, it looks like an uphill battle.
