Flover is now Korea AI Telecom · Licensed telecom carrier
Building telecom for the AI era
Korea AI Telecom (KAT) builds AI telecom infrastructure, and on top of it, phone-work automation and payment services. With two Korean telecom licenses, we issue phone numbers and run our own SIP switch.
“Are you closed? I’d like to book a consultation for tomorrow.”

The phone is opening up again
The phone is the oldest and most widely deployed voice interface. Voice AI is reopening it, but building a service on top takes numbers, lines, compliance and payments first. KAT lays that foundation so anyone building voice services in Korea can start on top of it.

Which one fits?
Product sites are in Korean.
Five layers, built on a telecom license
The lower the layer, the closer it is to infrastructure we own. Whichever layer a problem starts in, one point of contact diagnoses and fixes it.
Start where calls are missed
We find the problem in the moment a business misses a call, then pick the technology.
Automate to the finish
We don’t stop at answering. Bookings, payments and records get done.
Operate it ourselves
We issue numbers and run our own switch, so call quality and outages are ours to own.

The gaps in building voice services for Korea
We compared approaches, not companies. KAT covers everything from the line to the payment, with one point of contact.
| What you need | Global voice AI platforms | Traditional telecom & contact-center builds | |
|---|---|---|---|
| Korean numbers & lines | Separate carrier contract | Provided | Provided directly, as a licensed carrier |
| Korean complianceRecording & AI disclosure, caller ID, personal data | Left to you | Partly covered | Handled with you, as a licensed carrier |
| AI agent | Included | Bought separately | Included |
| How you deploy | Korean carrier integration is on you | Custom build | Pick a standard setup |
| Payments | Not included | Not included | In-call paymentBeta |
| When something breaks | Split across vendors | Split across vendors | One point of contact |
Infrastructure you can use today
Refined on the calls of 2,000 businesses. A 070 business number goes live in a minute, and the AI agent answers around the clock.
Keep your PBX. Add our lines and AI.
Connect KAT’s lines and AI agent to your enterprise PBX over a SIP trunk, without replacing it.
