Case Study

How iSmile Dental gives missed callers an immediate Croatian-language answer on its existing reception line.

Based in Split, iSmile Dental is Croatia's most state-of-the-art equipped dental clinic. With 17 doctors and one reception desk, it needed reliable cover for missed calls. Kingstone built a Croatian-speaking AI voice agent that records the context reception needs for a callback.

The challenge

iSmile Dental is a busy dental practice in Split with 17 doctors and one reception desk. Calls can be missed between patients, over lunch, or after hours. When that happens, a prospective or existing patient may simply call the clinic down the street instead.

How the deployment works

What happens when reception cannot answer

A missed call becomes a useful handoff instead of a blank entry in the call log.

01Call reaches iSmile Dental

The patient calls the clinic's existing reception number.

02AI answers in Croatian

Calls routed to missed-call coverage are answered without advertising a second number.

03Context is captured

The agent records the caller's name, reason for calling, and callback number.

04Reception follows up

Reception receives the captured context; urgent calls are surfaced for human attention.

iSmile Dental also received a dedicated dashboard to review call activity, follow-ups, deployment notes, and the metrics the team tracks.

The solution

Kingstone built a Croatian-speaking AI voice agent for the clinic's existing number. When reception cannot answer, the agent asks what the caller needs and records their name, reason for calling, and callback number. Reception can then follow up with context rather than a missed-call notification alone.

Built for a busy clinic, not a call centre

With 17 doctors and one reception desk, coverage had to fit around appointments, treatment, lunch, and after-hours calls. The agent needed to keep the existing number, speak Croatian, capture the right callback context, and make urgent situations visible to reception without asking the team to learn a second system.

The results

Figures below are from the first 90 days of live coverage. “Eligible” means calls routed into the missed-call coverage flow.

“We're a busy clinic with 17 doctors and one reception desk. Every call we used to miss just rang out to nothing. Now it's picked up in Croatian right away, and reception gets a name and a reason instead of an unexplained missed call.”
