    What Is the PSTN (Public Switched Telephone Network) and How Does It Work? What is the pstn

    Commercialization of the telephone began nearly 150 years ago, and the world started connecting to one another via the well-known (although rather unsightly) telephone lines. This telecommunications system evolved with underground copper wires, undersea telephone cables, communication satellites, and even a digital core network into the PSTN as we know it today.

    However, the PSTN was no match for the evolution of the internet, and it's been in a steady decline for the last decade.

    Curious what it is, how it works, and how it compares to modern-day communication solutions? If so, you're in the right place.

    What is the PSTN?

    PSTN stands for Public Switched Telephone Network, and it's the good ol' circuit-switched telephone network that's been in general use for the last century. The PSTN is also referred to as Plain Old Telephone Service (POTS)—yes, I'm totally serious. Awesome, right?

    It works by using underground copper wires …

    VoIP vs. Landline: 6 Things to Consider Before Building VoIP vs. Landline_ 6 Things to Consider Before Building.png

    What should your business use for its phone system: VoIP (Voice over Internet Protocol) or the classic landline telephone? It's a good question, and one you may have never considered before with landlines practically disappearing from residential housing.

    Seventeen years ago, more than 90% of US households had an operational landline phone. Fast forward to today, and it's now less than 40%. With smartphones becoming smarter (go figure) and a constant pocket companion, landlines are quickly losing relevance. And if the trend continues, there's no reason landline phones won't go the way of all technological relics—forgotten, much like VCRs, Walkmans, and floppy disks.

    Dying Landlines

    Landline Phones Are a Dying Breed, statista

    If you're a Gen Z member, there's a good chance you've never even used a landline phone before. Gasp!

    However, old habits die hard. Still, businesses debate VoIP vs. landlines. Which is more cost-effective? What solution has better call …

    What Is GPT-3: How It Works and Why You Should Care What Is GPT-3

    No, robots aren't taking over the world (not yet anyway). However, thanks to Generative Pre-trained Transformer 3 (GPT-3), they are well on their way to writing digital text as well as humans—and even better, in some cases.

    Human-equivalent writing sounds like a solid step on the path to a Terminator-like future...but cynicism aside, GPT-3 is establishing new ceilings for what AI and machine learning can accomplish.

    What is GPT-3?

    GPT-3, a new language model from the whizzes over at OpenAI, generates AI-written text that has the potential to be practically indistinguishable from human-written sentences, paragraphs, articles, short stories, dialogue, lyrics, and more.

    OpenAI trained GPT-3 on a massive corpus of text with more than 175 billion (yes, with a "b") parameters, making it the largest language model—ever.

    Lost? In non- technical terms, GPT-3 was shown how millions of people write and taught how to pick up on writing …

    The Fundamentals of VoIP (Voice Over Internet Protocol) The Fundamentals of VoIP (Voice Over Internet Protocol)

    Today's business communications are constantly changing. Years ago, it simply involved voice calls. Now, businesses use calls, messaging, email, mobile apps, chat, and video conferencing to communicate internally and externally on any given day.

    This evolution in communications not only changes employee and customer behavior—but it also changes the hardware and software required to make it happen. That's where VoIP (Voice Over Internet Protocol) comes in. VoIP empowers businesses to replace their outdated, traditional telephones with a complete communications package that happens all on the internet.

    Chances are you've used more than one VoIP-powered app already today. Examples include:

    • Skype
    • Google Hangouts
    • Zoom
    • WhatsApp
    • Facebook Messenger

    VoIP is changing the world of communications. With easy setup, low costs, and greater functionality, it's a technology that the future is embracing.

    Below, we'll deep dive into the nitty-gritty details of VoIP, including what it is, how it works, and why …
