Who are the ZeroCall agents?

Employees of Korea AI Telecom Inc. answer in person. They take calls the AI hands over on weekdays from 9:00 to 18:00 (Korea time); outside those hours the AI takes the request and leaves it as a text. If you need coverage after 18:00, we agree on it during rollout.

If we use the call handling service, can our own staff still take calls?

Yes. You choose whether calls handed over by the AI go to ZeroCall agents or to your own staff.

Do we have to cancel our current BPO?

No. Your BPO contract stays as it is and the AI is placed in front of it. Costs go down as fewer calls reach the BPO.

Can we keep our current main number?

Yes. The number stays the same and only the carrier that manages it changes, so there is no new number to announce to customers.

Do we need to replace our PBX and phones?

We add an integration line to your existing PBX, so you keep the same phones. If integration is difficult in your setup, we switch you to SIP phones or PC softphones.

Could testing cut off our current phones?

During the test we leave your existing lines and forwarding settings as they are and only add an integration line. Even if the integration does not work, your current phones are not affected.

Pricing is calculated individually based on the number of lines and the features you use. You can combine only the layers you need.

Can it connect to our CRM or internal systems?

Yes. Call logs, conversation content and summaries can be sent to your systems in real time through API and webhooks.

Fewer people on the phones and lower call charges,
by changing the structure

AI answers first and people take only the calls that are left. Agent headcount can come down by as much as the AI takes on, and number porting removes the charges on call-forwarding legs.

TELECOM COST

Charges on incoming calls come from the structure, too

With call forwarding, every leg where a received call is dialed out again is charged. With number porting, that leg does not exist.
