VOIP lets you make toll-free long distance voice and fax calls over existing IP data networks instead of the public switched telephone network (PSTN). Today businesses that implement their own VOIP solution can dramatically cut long distance costs between two or more locations. For the past 100 years people have relied on the PSTN for voice communication. During a call between two locations, the line is dedicated to the two parties that are using it. No other information can travel over the line, although there is often plenty of bandwidth available. Later, as data communications emerged, companies paid for separate data lines so their computers could share information, while voice and fax communications were still handled by the PSTN.
Today, with the rapid adoption of IP, we now have a far reaching, low-cost transport mechanism that can support both voice and data. A VOIP solution integrates seamlessly into the data network and operates alongside existing PBXs, or other phone equipment, to simply extend voice capabilities to remote locations. The voice traffic essentially “rides for free” on top of the data network using the IP infrastructure and hardware already in place.
the idea of VoIP is the hosted PBX. The IP-based PBX is usually software running on a computer based server. However, it often requires a forklift upgrade of the existing PBX, or at a minimum, an extensive software and/or hardware upgrade. An IP-based PBX is typically marketed to new installations where no legacy system is in place.
Ten years ago, who had thought there would be a small device in our hand giving so much within no time? Certainly, mobile phones have brought a paradigm shift in the history of technological development in the present era. Nokia has been the ambassador of all these changes coming with an array of innovative and entertaining handsets. “Nokia N series mobile phones” is the name of a new revolution in the coming future.
it has been a long time now since the launch of the first N-Series mobile handset. However, the N-Series after-effect is still very strong in us. We still can’t forget how radically our vision towards mobile phones did change with these brand new mobile handsets. All the handsets featured in this series are empowered by the latest in mobile telecommunication technology; in addition, they are stylishly designed and easy to use!
The Nokia N series mobile phones range is an iconic example of the fastest growing product category in the mobile space. The new addition in Nokia N series family include Nokia N95, Nokia N96, Nokia N98, Nokia and N96i. Nokia boasts of calling these handsets as the music phones which gives a new dimension of listening music on a phone. The recently launched Nokia N95 is the best manifestation of Nokia’s cutting-edge technologies till date. The handset resembles a miniature computer mainly because of its power and capabilities. An integrated 5 megapixel digital camera with auto focus, digi Continue reading »
The broadband technology in its inception has further ‘broaden and widen’ the so-called “information superhighway” allowing smooth traffic of all medium of data (voice, audio, graphics and video) with freer and faster access from their source to their destination. Major players of this technology are the Telecom and Digital Broadcasting Service (DBS) providers.
The broadband technology has created a lot of multiplier effects in the adjoining ICT technologies (Information, Communication and Telecommunications technologies) used in delivering service to their teeming subscribers. The main stream of this arrangement are the copper lines, cable-, modems and telephone-network upgrades are proceeding at varying speeds, depending on the company.
The responsibility lies on service providers to iron out any number of technological issues with the economies of scale in the broadcast and transmission distribution network before they can provide seamless, bug-free service in line of this new dynamic technology.
This consideration and the attendant deployment of the arrived business decisions on the chosen technology gave rise to digital satellite broadcasting and the rapid expansion of voice over IP (VoIP) technologies.
Also it further the growth of Wireless service providers, whose sector found the ways to speed the upstream, or return-path, delivery of data (data, voice and video)making the choice and option more attractive Continue reading »
One of the most importatnt tools to being successful in college is having the right kind of computer equipment. This should be researched and purchased before the big day starts. Whatever one buys, whether it is a desktop, a net book, or a laptop computer, one will have to obtain and purchase highspeed wireless internet. This may be added to tuition if you live in a dorm but apartment dwellers will be purchasing this on their own. Being able to research online is essential for a successful college course and even more so if it can be done from the comforts of home.
Success also comes from the books you have to purchase. Many students do not feel the need to buy the books for their classes, due to the expense, but this concept doesn’t provide them with all the necessary information to succeed at the class. Most tests and finals are book based and if one does not have the appropriate material to study beforehand, the student will end up either failing the class or barely passing. A student’s best bet is to buy the appropriate books before class starts and use them to their potential.
