Jaxtr has begun a private beta of its click-to-call VoIP system for social networking (SN) sites, and nabbed high-profile LinkedIn co-founder Konstantin Guericke as CEO to give the start-up a boost.Founded by entrepreneurs Phillip Mobin and Touraj Parang, Jaxtr bypasses all the headsets and hybrid phones by linking up tradition phones via VoIP and a call-back system.In other words, users register their phone numbers with Jaxtr and when someone clicks to call, they enter their phone number. The click activates the system which phones the clicker on their elected number and connects them to the Jaxtr user. Tech Watch made its first Jaxtr call to Parang, and it worked flawlessly, but in private beta fashion, our test of the service has not functioned properly. Guericke said the key control panel, which allows users to switch between routing Jaxtr calls to voice mail or as live calls, was not quite ready for release, but would be soon. Jaxtr users embed some code in their blogs or social network profiles, and voila. The code is tested with MySpace, Tagged, Friendster, Hi5, Xanga and Google’s Blogger. But Guericke said it should work with any service that allows embedding of code in a page. Jaxtr provides local phone numbers that allow callers to take advantage of the cost benefit of VoIP, eliminating international long distance charges. Twenty-nine national markets in Europe, the Americas and Asia are served. Initial countries range from United States to most of Western Europe to Brazil, Chile, Mexico and Australia.Guericke told InfoWorld a certain set of minutes would remain free for the time being, but he said their were many ways to monetize the service, such as via people who would be willing to pay additional per month for a set number of minutes; and via businesses, which could use it for easier access for customers/clients. Think lawyers and real estate agents, he said.He said SN was “all about connecting” but said the problem Jaxtr was addressing was that “you’re not always at you computer.” There are obviously many ways it could be used, and I’ve already begun thinking how InfoWorld readers could leave voice comments about stories by clicking if Jaxtr was tied in to one of the audio-blogging systems.The other standout thing with Jaxtr is that it is immediately — well, not for me quiet yet with initial trial — able to deliver VoIP to the masses by tying in to the one technology anyone wanting to be in touch already has — a phone.Interested in checking it out? Apply for private beta testing at Jaxtr.com, and a public beta is expected in one to three months, Guericke said. Can you say Google Phone anyone? Smart venture, guys. How long will it be before Google will make Jaxtr the next YouTube? Jaxtr will just need to prove it is as easy as pie, amass users and Google can’t live without it. VoIP made simple, with SN buzz? It will be a bidding war between Google, who could blend it into its properties Blogger and orkut quickly, and its Google Talk system, and Yahoo.Watch this space. Technology Industry
