Voice over IP (VoIP) Technology

VoIP communication concept. 3D rendering At TeleTraders, we work with a lot of technology on a daily basis, but the most common tech that we deal with is the Voice over IP (VoIP) phone. In the modern office, the VoIP phone is the ubiquitous piece of hardware that every office worker has an intimate relationship. With this in mind, we want to talk about all things VoIP technology and also some of the more common brands that you are likely familiar with.

What actually is Voice over IP?

Voice over IP, also known as IP telephony, is a set of methods and technologies designed for the reliable delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks such as your office network or the Internet. VoIP technology follows decades of standard analog voice communications through the Public Switched Telephone Network (PSTN), which required a hardwired physical connection to the local telephone company. Given the nature of the PSTN ecosystem of the times, the requirement for physical access to their network meant that competition was incredibly sparse, and this leads to costly service fees. VoIP, given at the most basic level, only requires a connection to the Internet either through a local Broadband provider or the Internet Service Provider (ISP) at your office. This opened the floodgates for a competitive market and has led to drastically reduced service fees and also pushed service performance and reliability to the next level as homes and companies are able to switch VoIP providers fairly easily compared to the past.

VoIP Business Phone Systems and SIP Trunking Technology

On the left-hand side of the diagram, we can see some of the more common components that you’re most likely intimately familiar with, including mobile phones, desktop and laptop computers, tablets, desktop phones, “softphones,” and the ATA gateway, which converts an analog signal into a digital signal. In the middle of the diagram, we see the Session Initiation Protocol (SIP) trunk, which connects your office IP Private Branch Exchange (PBX), sometimes referred to as the VoIP server, to your office internet service provider network. In a nutshell, the SIP trunk is a digital grouping of one or more phone lines connecting to your VoIP provider network. This technology is akin to the older T1 service that businesses purchased in the past to connect several landline phone lines to the PSTN. On the right side of the above diagram, we see the unique difference between the older hardwired landlines compared to the VoIP era. Instead of physically connecting each landline to the local PSTN, we can see that the VoIP SIP trunking allows the modern office to take advantage of the vast competition available in the VoIP world. Using the Internet, the VoIP SIP trunk is able to connect to any number of VoIP providers on the Internet. This allows your office to make CapEx and OpEx decisions that best suit your business goals and budgets.
