Why missed calls cost real money
For an auto shop, an HVAC company, a clinic or a salon, a missed call is not a missed message — it is a customer who calls the next business on the list. Voicemail does not recover that customer, and hiring a full-time receptionist to cover evenings and weekends rarely pencils out for a small operator.
Conserja answers every call, at any hour, in the caller's language. It handles the conversation, captures what the business actually needs to know, books into the calendar and sends an SMS confirmation before the caller hangs up.
What it does
- Answers 100% of calls, 24/7 — no voicemail, no hold music, no after-hours gap.
- Books appointments — straight into the business calendar during the call.
- SMS confirmations — the caller gets a text before they hang up.
- Bilingual English and Spanish — the agent switches to the caller's language.
- Live in about 15 minutes — from signup to a working agent on a real number.
How we built it
Conserja is a real-time voice AI stack: telephony, streaming speech recognition, an LLM reasoning layer and streaming speech synthesis, wired together so the round trip stays inside the window where a human caller still feels like they are in a conversation rather than talking to a machine.
Latency is the entire engineering problem. Every component in that chain wants to buffer, and buffering is what makes voice agents feel broken. The build is an exercise in streaming everything end to end, cutting handoffs, and failing gracefully when a model call runs long.
The second problem is scope. A voice agent that answers freely will confidently invent prices, promise appointment slots that do not exist and answer questions the business never authorized. Conserja runs behind a scope gate and books only against real calendar availability.
