What we deliver
- Inbound and outbound calling with natural, low-latency speech
- Appointment booking, order status, FAQs and lead qualification

- Live in weeks on Twilio, Exotel, Plivo or SIP
- Grounded in your own knowledge base to avoid wrong answers
- Costs a fraction of a call centre seat
Where voice agents pay off first
Clinics and hospitals (appointments, reminders), real estate (lead qualification and site-visit booking), hotels and restaurants (reservations), coaching institutes (admissions enquiries) and e-commerce (order status, returns). We start with one high-volume flow and expand.
How the agent works
Speech-to-text, an LLM grounded in your data with tool access (calendar, CRM, order APIs), and text-to-speech tuned for natural pauses and interruptions. Guardrails limit what the agent may promise, and every call is transcribed and summarised.
Quality you can hear and measure
We test with real call recordings, tune for your accents and terminology, and track containment rate, booking conversion and customer sentiment after launch.
