Curious minds, attention, please! Today, we’re diving into a topic that might initially come across as a bit fancy: PSTN-based calling services. However, fear not, as we’re here with the sole aim of elucidating it in the most straightforward manner imaginable. Let’s embark on this journey of unraveling the mystery together.
What’s PSTN Anyway?
PSTN stands for Public Switched Telephone Network. Sounds big, right? But it’s just the old-style phone system that’s been around forever. Remember those phones with cords? Yep, that’s the one. It’s like the original way our voices traveled from one phone to another.
How Does PSTN Calling Work?
Imagine your voice turning into tiny signals. These signals travel through phone wires like little messengers. They jump from one telephone pole to another, making stops at big switching centers. It’s like a relay race, where each center passes on your message until it reaches the person you’re calling.
