Case Study | How KER Increased Qualified Leads 10× During the Summer Enrollment Season with AI Outbound Calling
Challenge
In China, July and August are the peak enrollment months for children's summer camps, coding classes, and STEM training programs. Most parents make enrollment decisions within a short period, making speed-to-contact a key competitive advantage.
For KER, outbound calling remained the most effective channel for:
- Promoting trial classes
- Qualifying prospective parents
- Confirming appointments
- Reducing no-shows
- Following up after classes
- Driving additional course enrollments
However, their traditional call center had reached its limit.
- 20 human agents
- Around 4,000 outbound calls per day
- Approximately 80 qualified leads daily
The marketing team had far more leads than the sales team could contact, causing valuable opportunities to be lost during the busiest enrollment season.
Solution
KER deployed the Kontactix AI Outbound Call Center with 200 concurrent AI voice agents, working alongside its existing sales team.
Instead of replacing human agents, AI handled repetitive conversations while seamlessly transferring interested parents to sales representatives.
The result was a scalable human-AI collaboration model.
1. 10× More Customer Conversations
The AI voice agents automatically contacted parents, introduced trial classes, answered common questions, and qualified customer intent.
- 20 human agents
- ~4,000 outbound calls/day
- ~80 qualified leads/day
- 200 concurrent AI voice agents
- 40,000+ outbound calls/day
- 800+ qualified leads/day
- 20 human agents focus on closing deals from the 800+ qualified leads
When parents expressed strong interest, the AI automatically detected buying intent and warm-transferred the conversation to a live sales agent, ensuring the sales team spent their time only on high-value opportunities.
Parents could also schedule trial classes directly during the AI conversation without waiting for a callback.
2. Automatically Recover Missed Trial Classes
Missing a scheduled trial class doesn't always mean losing a customer.
When parents failed to attend, the AI automatically initiated a friendly follow-up call to understand why.
Depending on the response, the AI could:
- Identify the reason for the absence
- Offer alternative dates and times
- Reschedule the trial class automatically
- Update the CRM instantly
This proactive follow-up helped recover many potential enrollments that would otherwise have been lost.
3. Improve Attendance with Automated Class Reminders
Parents are busy, especially during the summer holiday.
The AI voice agent automatically reminded parents before each scheduled trial or class, confirming attendance and reducing forgotten appointments.
This simple automation significantly improved attendance rates by 18% while eliminating hundreds of manual reminder calls every day.
4. Continue the Customer Journey After Enrollment
The AI didn't stop after enrollment.
It continued engaging families through automated follow-up calls to:
- Collect feedback on courses and teachers
- Measure customer satisfaction
- Identify service issues early
- Recommend advanced courses
- Discover upsell and cross-sell opportunities
Every interaction generated valuable customer insights while helping KER strengthen long-term relationships with parents.
Why AI Worked
The biggest improvement wasn't simply making more calls.
It was ensuring every parent received timely, consistent communication throughout the entire customer journey.
From the first marketing call to post-class follow-up, AI handled repetitive tasks at scale while human advisors focused on conversations that required empathy, expertise, and closing skills.
