What is PSTN?
PSTN is the traditional telephone network — the old phone system.
The problem
PSTN (Public Switched Telephone Network) is the legacy network of phone lines, carriers, and numbers. It works, but it is expensive, slow to provision, and tied to numbers and carriers. Interactalk's planned direction is browser-first, precisely to avoid PSTN as the only rail.
How Interactalk helps — planned
PSTN (Public Switched Telephone Network) is the legacy network of phone lines, carriers, and numbers. It works, but it is expensive, slow to provision, and tied to numbers and carriers. Interactalk's planned direction is browser-first, precisely to avoid PSTN as the only rail.
What it looks like in practice
Example: a traditional phone system needs a number, a carrier, and a PBX. A browser call needs a link and a browser.
What you get
Legacy
The old phone network.
Number-dependent
Needs numbers and carriers.
Slow to provision
Numbers take time and paperwork.
Not the only rail
Browser-first is the planned alternative.
How it works
1. Connect — a customer clicks Talk in a browser, no app, no number needed. 2. Configure — you set the agent, rules, and workflows once. 3. Communicate — the AI agent, declaring itself as AI upfront, listens, answers, and acts. 4. Optimize — every conversation becomes a booking, ticket, CRM update, or follow-up, not just a recording. This flow is the Interactalk direction; the live product is still in development, and no live call is claimed here.
