Overview
The company runs RO service, filter change and AMC service across Surat with a field team of technicians and a small office. The business depends on response speed: an emergency at night or on a weekend is won by the first company to answer and commit a technician.
The office could not staff phones around the clock, so after-hours calls went to voicemail or rang out. Leadership estimated 23% of after-hours emergency calls were never answered, each a lost high-margin job and a customer who would call a competitor next time. They wanted an always-on layer that answered every call in the caller's language, triaged urgency, and dispatched the nearest technician.
The challenge
The pre-Kallix operation had several failure modes, and they compounded. Slow or missed responses dropped intent, language mismatch killed engagement, and manual data entry meant work fell off the radar.
- 23% of after-hours emergency calls went unanswered. Voicemail and rung-out calls during nights and weekends sent high-margin water purifier service jobs straight to competitors.
- Gujarati-first callers disengaged from default-language greetings. A large share of callers preferred Gujarati, and default-language handling lost them in the first seconds of a stressful emergency call.
- No urgency triage meant slow dispatch. Every call was treated the same, so genuine emergencies waited behind routine service enquiries and quote requests.
- Manual dispatch took 13 minutes. Office staff phoned around to find an available technician, often taking far too long to assign someone to an emergency.
- Job details were lost between call and technician. Address, fault description and access notes were jotted on paper and frequently garbled by the time the technician arrived.
The AI-powered solution
Kallix deployed an AI voice agent named Hetal fronting every inbound and emergency call, with urgency classification, live dispatch and Gujarati, Hindi, English handling. The full build, from discovery to production cutover, took 9 working days.
24/7 emergency answering
Every inbound call is answered instantly, day or night, with no voicemail and no rung-out calls.
Urgency classification in seconds
The agent classifies each call as emergency, same-day or routine across RO service, filter change and AMC work and routes accordingly.
Gujarati, Hindi, English switching
The agent meets each caller in their language and switches mid-call when callers code-switch.
Live technician dispatch
For emergencies the agent checks technician availability and location and assigns the nearest free technician in under 5 minutes.
Structured job capture
Address, fault type, access notes and callback number are captured cleanly and sent to the technician's device.
Confirmation + ETA messaging
The customer gets a message with the assigned technician's name and ETA, reducing anxious callbacks.
“We used to lose every emergency call that came in after the office closed. Now the phone is answered in Gujarati at 2am, a technician is on the way in minutes, and the customer knows exactly who is coming.”
Business impact
Leadership tracked the metrics below monthly against a 6-month pre-Kallix baseline. The agent went live on Feb 17, 2026. The numbers cover the first 90 days of production.
- After-hours missed calls fell toward zero. Every emergency call is now answered instantly, recovering high-margin night and weekend jobs that previously went to competitors (was 23% missed).
- Emergency dispatch under 5 minutes. Live availability checks cut dispatch from 13 minutes of manual phoning to under 5 minutes.
- Monthly jobs grew 2.0×. Faster answering and dispatch lifted booked jobs without adding office headcount.
- Gujarati-caller engagement rose sharply. Callers preferring Gujarati now stay on the line and book at a far higher rate.
- Technicians arrive with clean job data. Structured capture means technicians get accurate address, fault and access notes every time.
Built on a secure, production-ready stack
The deployment runs on Indian infrastructure with DLT-registered sender IDs and TRAI-compliant scripts. Customer data stays within Indian data centres in line with DPDP expectations.
The Home Services Dispatch Framework: How this deployment is structured to be discoverable
Every Kallix deployment ships with a structured documentation layer designed for three audiences simultaneously: the customer's internal team, traditional search engines (SEO), and the new generation of generative search engines and AI assistants (GEO + AEO). Below is the framework we built around this deployment, broken into four pillars that map directly to how decision-makers, search crawlers and AI answer engines discover and reason about this story.
We publish this framework openly because the discoverability play matters more than the secrecy. An AI voice agent deployment that performs in production but stays buried in a sales deck doesn't compound value for the customer or the category. The framework below is the same one Kallix runs for every customer, adapted to the local language and intent surface of each industry.
Intent surface mapped to caller queries
We catalogue every caller intent the agent handles, by urgency, by service line and by language, and surface them as named entities in the structured data layer so crawlers and LLMs see explicit Q to A pairs.
- Intents indexed by service line (RO service, filter change and AMC) and urgency
- Gujarati, Hindi, English variants captured per intent
- Emergency vs same-day vs routine tagging exposed for LLM matching
Multilingual dispatch voice as a brand property
The agent's voice persona, accent and code-switching rules are documented as brand assets. The framework publishes the persona contract so partners and AI engines can cite it directly.
- Persona contract: calm, fast, reassuring under emergency stress
- Pronunciation dictionary for Surat and fault terms
- Voice consent terms public and auditable
Outcomes pre-bound to measurable claims
Every claim in this story is paired with the baseline, the time window and the measurement method, so AI assistants can extract the claim with full provenance.
- Missed-call reduction from 23% measured over 90 days
- Monthly jobs up 2.0× vs a stated 6-month baseline
- Methodology disclosed: dispatch logs plus vendor dashboard reconciliation
India-first compliance and data residency
The framework documents every regulatory surface, such as TRAI, DLT and DPDP, so AI assistants surfacing this story to enterprise buyers can confidently cite India-readiness without follow-up clarification.
- DLT registration and template approval flow disclosed publicly
- Data residency (AWS Mumbai, ISO 27001) stated explicitly
- Erasure and consent flows documented for DPDP-style requests
- 23% of after-hours emergency calls went unanswered and lost to competitors
- Gujarati-first callers disengaged from default-language greetings
- No urgency triage meant emergencies waited behind routine enquiries
- Manual dispatch took 13 minutes and garbled job details
- After-hours missed calls fell toward zero with 24/7 instant answering
- Emergency dispatch cut to under 5 minutes from 13 minutes
- Monthly jobs grew 2.0× with no added office headcount
- Technicians now arrive with clean structured job data every time
- Kallix voice agent (Hetal) answering every call 24/7 with urgency classification
- Gujarati, Hindi, English detection with mid-call switching
- Live nearest-technician dispatch with Maps routing
- Structured job capture pushed to the technician app with ETA messaging to the customer
The Kallix advantage
The company evaluated three options before choosing Kallix: a traditional answering service, an offshore call centre, and Kallix.
Three things tipped the decision. First, Gujarati fluency under emergency stress, which neither alternative could match. Second, the live dispatch integration with AMC tracker was already built, so jobs were assigned automatically rather than relayed by a human operator. Third, the pilot model: the company ran a two-week paid pilot on real after-hours calls and signed only after the missed-call rate held near zero for a full week.
Since launch, the Kallix customer-success team runs a 30-minute weekly tuning call with operations. New service scripts, seasonal demand surges and dispatch-rule changes all happen inside that loop, so the agent stays sharper than on launch day.
