VoIP (Voice over Internet Protocol) is a digital network system that allows people to make phone calls over broadband Internet connections rather than traditional land lines. A VoIP engineer creates, tests, installs, and maintains both small business VoIP systems and large regional VoIP networks. To implement the latest technologies, engineers rely on their expert knowledge of computer science, digital audio hardware, and VoIP software. They also collaborate with IT professionals and system administrators to demonstrate how to run systems as efficiently as possible.
The majority of VoIP engineers work for telecommunications companies that provide services to businesses and residents in a specific area. They create schematics for new hardware like analog-to-digital converters and stand-alone VoIP phones. Professionals also develop software that enables users to make phone calls directly from their computers.
Experienced VoIP engineers set up codecs, which convert speech and other audible noises into digital signals. They tweak programs to ensure that codecs can be sent across a network quickly and correctly, and that the receiver’s phone can decode them back into audible signals. Extensive research and training are required to comprehend the properties of codecs and digital transmission. Because technologies change on a regular basis, engineers must read industry journals and participate in continuing education to stay current on new developments and trends.
To manage its local area network, a large corporation might hire a full-time VoIP engineer. A VoIP engineer working for a private company typically spends more time maintaining and troubleshooting systems than a telecommunications company employee. He or she configures wireless local area networks, tests connection speeds, and inspects Ethernet cables and ports. When an IT employee is faced with a difficult problem involving the company’s VoIP system, the engineer can diagnose and resolve the issue.
Although there are no specific educational requirements for becoming a VoIP engineer, having a bachelor’s degree or higher in a related field can greatly increase one’s chances of getting into the field. Many large telecommunications companies, in fact, require a degree in computer science, network engineering, electrical engineering, or programming. A prospective VoIP engineer can also improve his credentials and job prospects by taking voluntary certification exams offered by private organizations. New engineers typically work as junior or assistant engineers for several years to gain experience and master their skills. In time, successful employees may be promoted to senior engineers, supervisors, or outside consultants.
