From €29 a month, no new number, no new provider; every call sits in your list with a transcript.
SMarTrPhone is the AI phone assistant from SMarTrAgents for small businesses: the assistant Ava takes calls, enters appointments and files every conversation with a transcript in your list; Starter costs €29 a month for up to 100 minutes, Professional €99 for up to 400 minutes, Business €199 for up to 1200 minutes.
Every call that nobody answers in a small business is a job that lands somewhere else; SMarTrPhone answers it.
In small businesses the phone rings at the most awkward times: in the middle of the work on the ladder, with the customer on site, after close of business. During the day, too, the hand stays above the receiver when a machine is running or a customer is standing in the shop.
Behind the phone assistant Ava stands a system that takes the call, speaks with the caller and places the result in your system as an appointment, callback request or note. You stay reachable on your own number and your own line, and no new provider comes in.
A call at SMarTrPhone runs in four steps: Ava introduces herself, asks what the caller wants, confirms name and number, and files appointment, callback request or note with a full transcript in your list.
The Fritz!Box forwards the call to Ava when nobody can pick up themselves, and Ava introduces herself as an AI assistant.
Ava asks what the caller wants and leads the conversation along the flow you have set up for it.
Ava repeats the name and the callback number so the entry in your list is right.
Appointment in the calendar, callback request in the callback list or a note, each time with a full transcript in the call list.
Ava: "Good day, you are speaking with Ava, the AI assistant. How can I help?"
Caller: "I would need an appointment for the measurement inspection."
Ava: "Gladly, Tuesday at 9 am would be free. May I note your name and callback number?"

At SMarTrPhone Ava decides nothing on her own: you read the transcript, you call back, you confirm the appointment.
Every conversation lands in your call list with number, request and full transcript, and whoever wants a call back stands in the callback list with phone number and request. You read up in peace on what was said on the phone and decide what comes of it: an appointment gets confirmed, a callback done, an enquiry passed on.
Appointments, callbacks and notes from the phone land in the AI ticket system with CRM SMarTrDesk, where you work through enquiries from phone, email and chat in one place.
