Before AI-powered phone agents, cloud contact centers, and Unified Communications began transforming the telecommunications industry, one technology fundamentally changed how people made phone calls: Voice over Internet Protocol. In the previous article, we explored PSTN, the traditional telephone network that connected the world for more than a century. The next logical step in our series is answering another essential question: What is VoIP?
We created this new article series to explain telecommunications in plain English. Each article answers a common “What is…” question without unnecessary jargon. The goal is to help business owners, IT professionals, telecom engineers, and anyone curious about communications understand how modern phone systems work. We begin at the very foundation of telecommunications: What is PSTN?
In the previous article, we explored PSTN, the foundation of global voice communication and the system that defined telephony for over a century. While this legacy infrastructure enabled reliable connectivity, it also exposed the limitations of circuit-switched communication in a rapidly evolving digital landscape. To move forward, it becomes essential to answer a key question: what is SIP, and how does it enable modern, flexible communication over IP networks?
The Public Switched Telephone Network (PSTN) is the foundation of global voice communication. Long before internet-based communication became widespread, PSTN enabled reliable, real-time conversations across cities, countries, and continents.
In today’s fast-paced business environment, effective communication is crucial for success. Choosing the right phone system for your business is an important decision that can significantly impact your daily operations and overall efficiency. When it comes to phone systems, two popular options to consider are hosted PBX and onsite PBX. In this article, we will explore the key differences and help you make an informed decision for your business.
Communication drives your business forward. Client and vendor inquiries begin through phone conversations. Teams regularly meet in conference calls to examine information and brainstorm ideas. Establishing a clear communication process helps your employees increase their productivity. In order to build such a process, you need a Unified Communications (UC) and Collaboration platform, SIP trunking, DIDs and internet access.
This article is a beginner’s guide to VoIP. Reading forward, you will find out what is a VoIP phone number. You will understand why so many businesses prefer VoIP over the old PSTN telephony. You will get familiarized with the terminology, discuss the differences between fixed and non-fixed VoIP and the benefits of each. Finally, you will find the answer to the most frequently asked questions. We hope that, by the time you are done reading, you will find it easier to determine if your business needs a VoIP phone number. And also you’ll find out how to choose the best service provider to meet your needs.
