Agent live now ยท NVIDIA Nemotron on Pipecat Cloud

The voice agent for
the calls you can't pick up.

SecondLine answers a small business's missed calls, remembers the caller, takes the order through typed tools, and texts the owner โ€” then tests and improves itself on every call.

Real phone number. Real agent. Pick up your phone and talk to it.
The silent profit leak

Local businesses lose money every time the phone rings unanswered.

It rings far more than they can answer โ€” and the callers don't leave a message. They call the next shop.

Production architecture, not a chatbot

A reliable voice employee for the second line.

Telephony in, typed tools out. The model is never trusted to invent business state โ€” it can only act through tools that read and write a real database.

Dashboard of what happened

๐Ÿง  Persistent memory

Recognizes returning callers by number, recalls past orders and constraints. "Same as last time, but no lilies โ€” my mom's allergic" just works.

๐Ÿ›ก๏ธ Safety-aware

Allergens on file are enforced at the tool layer โ€” the agent physically cannot add a bouquet a caller is allergic to.

๐Ÿงพ Owner workflow

Every order becomes a structured task โ€” customer, request, confidence, due time, next action โ€” with an SMS summary.

๐Ÿ™‹ Knows its limits

Refunds, complaints, impossible asks โ†’ escalates to a human instead of guessing. Never invents prices or policy.

The part that wins

It finds and fixes its own mistakes.

Every call is logged, tested, scored, and used to improve the next version โ€” with real automated test calls (Cekura) and an evaluation harness, not vibes.

  • Failures become fixes. Each failed call โ†’ a structured bug report โ†’ a prompt patch, validation rule, escalation rule, or memory update โ†’ re-run.
  • Real automated test calls. Cekura places live voice calls, scores transcripts, and surfaced a production bug our local tests couldn't โ€” which we fixed and re-verified.
