Every call answered.
Built for Boston businesses.
A managed AI receptionist that picks up every call in a natural voice, books real appointments into your calendar, and gets you the callback every time — around the clock, on the number your Boston customers already dial.
A missed call in Boston is a booked competitor.
When a radiator quits in a Somerville triple-decker in January, or someone's booking a cut before a Seaport wedding, they call — and in a market this dense, the next name in the search results is one tap away. Voicemail doesn't book jobs, and a phone menu can't hold a conversation.
LinearZeta puts a managed voice agent on your line instead: it picks up on the first ring, holds a natural conversation, answers only from your own information, and books the appointment while the caller is still on the phone. The moment someone needs a person, it transfers to one.

What a LinearZeta agent handles.
Built and run for you — no software to install, no scripts to write.
Answers every call, 24/7
After hours, during the lunch rush, while your team is on a job — every caller gets a real conversation, not voicemail.
Books appointments for real
Straight into your calendar — your own Google Calendar on any plan, Square Appointments on Starter and up, or Jobber job requests on Standard. Callers can reschedule or cancel by phone too, without needing a booking reference. No calendar yet? We provision one.
Gets you the callback, instantly
When a call needs your judgment — a quote, a diagnosis, a consult — it takes a name and callback number and emails you instantly.
Hands off to a human
Upset caller, emergency, or anyone who asks for a person — transferred live to you or your on-call line. Every call opens with a clear AI disclosure.
Built for the businesses that run Greater Boston.
