Call answering
A voice layer that picks up, asks the right questions and keeps a record.
An AI receptionist for calls, bookings and after hours
An answering layer for calls, bookings and after hours enquiries, built the way we built Call24.
Problems we solve
Calls arrive while everyone is busy
The person who should answer is on a job, in a room, or off for the night.
A missed call is a missed booking
The caller does not leave a useful message, and the day is already full.
After hours is a voicemail box
The question, the booking and the urgent handoff all wait until morning.
What we build
Booking
Appointments written into the calendar or CRM you already use.
After hours
The same path at night, with a person on the calls you mark as urgent.
Call24
Brown Tech's own receptionist. The same team that built it builds this work.

Brown Tech product
Call24 is Brown Tech's own AI receptionist for home service teams who miss calls on the job or after hours. It answers with your greeting, captures job details and can book a slot when Google Calendar is connected. Every call is saved in the call log so the office can follow up.
Voice AI, hospitality
We worked on a voice receptionist for hotels that answers guest calls 24/7 in multiple languages. It handles reservations, changes and cancellations, property questions, and room upgrade offers drawn from live inventory. It connects to the property management system, with real time call analytics for the team.
