01Client Overview

The client.

Medical and dental clinics consistently lose revenue to no-shows, cancellations and empty slots. The client needed an outbound system that could call patients automatically, hold a natural conversation in Urdu or English, capture the outcome and stay strictly inside a clinical script.

02Business Challenges
  • Missed appointments and lost revenue
  • High cost of manual phone outreach
  • Limited front-desk capacity
  • Poor patient engagement on email/SMS
  • No automation across clinic locations
03Project Goals
  • Automate outbound appointment recovery calls
  • Sound human, in both English and Urdu
  • Stay strictly on-script — no medical advice
  • Log every call, outcome and intent
  • Give staff a live monitoring + override dashboard
04Solution Overview

How we built it.

A fully automated AI voice calling platform. Campaigns are loaded from Google Sheets or the dashboard; the system dials patients, transcribes their speech, runs the response through a script-controlled GPT layer, and replies with an ElevenLabs voice. Every call is logged with full analytics.

09Scalability

Stateless calling workers, queue-based campaign engine and per-clinic configuration mean new clinics — and entire clinic groups — can be onboarded without changing the core system.
