These are live agents, not recordings. The current demo agents were built for Indian businesses and speak Hindi mixed with English; your agent speaks the languages your callers use.

What it does

What the answering service handles on each call.

Answers questions

Hours, location, prices you publish, what to bring, how to pay: the agent answers from the instructions you give it.

Takes messages

It collects the caller's name, number and reason for calling. Every call has a recording and a transcript.

Books appointments

Agents support MCP and tool calling during a call. Connect your booking calendar as a tool and it can book, move or cancel a slot.

Transfers urgent calls

The agent can transfer the call live to a person on your team.

Speaks the caller's language

Valmiki STT detects the spoken language automatically. One voice can speak across languages, and a cloned voice carries across languages too.

Sends you the details

It connects to HubSpot, Salesforce, n8n, Zapier and Make. Messages and call details go to the tools you already use.

Price

One flat price: $0.055 per minute.

You pay for the minutes callers spend on the line, whichever language they speak and whatever the hour.

$0.055 per minute is the published price for agent calls. Telephony you connect from your own provider carries no Sonex minute charge. See pricing or the cost calculator.

Medical

Medical answering service and virtual receptionist.

For clinics and practices, the agent books, moves and cancels appointments, answers questions about hours, location and insurance you accept, and takes messages for the care team. Patients who prefer Spanish, Hindi, Arabic or another language are answered in it.

Set clear limits in its instructions: it does not give medical advice, and anything that sounds urgent is transferred to your on-call number or the caller is told to call emergency services. Before go-live, read what makes voice AI HIPAA compliant.

After hours

After-hours answering service.

Point your line at the agent when the office closes, or only when every line is busy. It answers nights, weekends and holidays, takes the message and books the next available slot, so callers are not sent to voicemail.

Calls that cannot wait until morning are transferred live to whoever is on call. Everything else is waiting for your team as a recording, a transcript and, through n8n, Zapier or Make, a message in the tools you already use.

Before you go live

Tell callers they are talking to an AI.

Write the opening line yourself. The AI disclosure and recording-notice scripts have wording in the languages people call in, and AI calling rules by country covers disclosure and recording consent country by country.
