PSTN stands for Public Switched Telephone Network — the traditional copper-wire phone system that has connected phone calls for over a century. When you use a landline phone, your call travels over the PSTN through a network of switches and physical lines.
PSTN is reliable but expensive and inflexible. It requires physical phone lines, per-line rental fees, and expensive long-distance charges. That's why businesses are switching to VoIP, which delivers the same call quality over the internet at a fraction of the cost, with far more features. RingVersa VoIP plans start at $14.95/mo and include everything PSTN can't offer.
Key Features
Everything you need for professional business communication
Traditional Phone Lines
PSTN uses physical copper wires and circuit-switched connections — the original phone network.
Reliable but Rigid
PSTN is reliable for voice calls but can't easily add features like auto attendant or voicemail-to-email.
Expensive to Scale
Adding lines requires physical installation and per-line rental fees — costly and slow.
No Built-in Features
PSTN offers basic calling only; features like call routing and mobile apps require extra hardware.
