![]() ![]() Standard SIP based VoIP phones have emerged to fill this need. While the iPhone is setting the standard for mobile, there’s still a need for simple, reliable, and cost effective home and office phones. Companies like and have emerged to provide business PBX phone service via the Internet for a low monthly fee. ![]() It is no longer necessary for small business owners to deal with the complexity and expense of managing their own phone system. Telephone answering machines and PBX have become applications that run on the server. One effect has been the shift toward cloud computing. The Internet with its open standards and vastly superior content has loosened the grip of the PC. Some 10 years later, Apple transformed the cell phone industry by making the phone just another app that ran on a powerful mobile computer with a breakthrough user interface. Telepresence was marketed as a way to reduce the cost of business travel. Multiple soft-phones and audio/video communication platforms were born by solving the problem of streaming high quality audio/video across the Internet to PCs (like Skype, iChat AV, and Magic Jack). ![]() As the global Internet emerged, there was leverage in making the phone just another application that ran on the PC. More software leading to ever more investment made it very difficult for any platform that wasn’t a PC to compete on features and price. No other PBX works with as wide a selection of phones, and this has driven the adoption of SIP based VoIP as the industry standard.īy the 1990s, the PC was king. Another response to the complexity of proprietary phone systems is the emergence of Asterisk, a powerful, free, open source PBX that works with phones from several major manufacturers. CSTA has also been extended to SIP phones in the form of uaCSTA (User Agent CSTA), but US adoption has been slow. In response, European standards organizations developed CSTA (Computer-Supported Telecommunications Applications) as a model for standardizing the computer interface to PBX systems. With hundreds of proprietary digital phones and PBX systems, Windows TAPI (Telephone Application Programming Interface) has traditionally dominated CTI by providing a common API that phone and PBX vendors could write to. These numbers are expected to flip over the next 5 years so that by 2015 approximately two thirds of all installed phone lines in the US will be VoIP. Market research from 2010 suggests that approximately one third of installed phone lines in the United States were using VoIP while two thirds still used the legacy PSTN. There’s a quiet revolution underway as the old 4 kHz narrowband phone system is being disrupted by a combination of cell phones and Internet phones with advanced features and HD Voice. ![]()
