An AI that answers the phone for you, around the clock

An AI that answers the phone is an AI phone agent connected to your existing line. When a call comes in and nobody picks up (or from the first ring, your choice), it takes the conversation:

1. 1It greets the caller with your custom greeting and your business name.
2. 2It listens to the request in natural language, with no keypad menu.
3. 3It asks your qualifying questions (topic, address, urgency, availability…).
4. 4It captures everything: full transcript, detected intent, callback number.
5. 5It notifies you by email and SMS with a ready-to-handle call sheet, and transfers the call when your escalation rules apply.

The output isn't a voicemail to replay — it's a structured sheet you read in ten seconds between two appointments.

Voicemail leaves the caller alone with a beep: many hang up, and those who do leave a message rarely state the reason or a usable number. An IVR forces callers to translate their request into menu digits and adds no information.

An AI that answers the phone does the opposite: it talks, follows up when something is missing and repeats back to confirm. That's the difference between a lost call and a qualified request.

The assistant introduces itself as your business assistant; it never claims to be a person. Conversation stays fluid thanks to sub-second latency on real-time voice models, and the caller gets what they came for: to be heard, to leave their request, and to know someone will call back.

Beyond messages, the AI can book the appointment itself. Connect your calendar (Google Calendar, Outlook) and it reads real availability, offers a slot to the caller and creates the event during the call. You find the appointment already booked, with no email ping-pong.

• Your current number: set up call forwarding (always, on busy, or on no answer). No number change, no hardware.
• Your instructions: what the assistant should ask, who to transfer to, your business hours.
• 15 minutes of guided setup, then a first test call.
