How calls work

This is what a caller experiences on a CSflow call, start to finish, and the honesty rules the agent operates under at each step. It applies to the demo line today and to calls the agent answers for a business.

Last updated July 11, 2026

Pickup: the disclosure

The agent answers every call the same way, before anything else, with this exact pre-recorded line:

Hey, this is the Crest Agent. I'm an AI with Crest Systems, and quick heads up, the call's recorded. More on that at crestsystems dot ai. Not okay with it? Just say so, or hang up anytime. Otherwise, what can I do for you?

Two things about that line. It is versioned, not improvised: the AI does not get to rephrase its own disclosure, and changing a word means a new recorded version. And the system around it fails closed: if the recording pipeline cannot start, or the disclosure cannot finish playing, the agent apologizes and ends the call rather than talking to anyone unrecorded or unannounced.

The conversation

After the disclosure, there is no fixed script. The agent is instructed to talk the way a good, competent tradesperson talks: direct, plainspoken, short turns, one question at a time. Concretely:

  • Your question comes first. If you open with a question, it answers it before asking you anything.
  • It qualifies as it goes. It finds out who is calling and what they need; the questions a booking or a handoff requires, not a form read aloud.
  • It admits what it does not know. Rather than guess, it says so and flags the question for a human to cover in follow-up. It never invents an answer.
  • Asked if it is AI, it says yes, plainly, and keeps going. No lecture, no defensiveness.
  • Asked about price, it describes the shape (a flat monthly hire, not per-minute metering) but quotes no numbers; specifics are what the human follow-up is for.
  • Asked to stop recording, it is honest that it cannot switch the recording off itself, and offers to end the call and flag the request, including deletion, to the team.

Booking an appointment

When the conversation gets to scheduling, the agent uses real tools against a live calendar and narrates what it is doing instead of going silent:

  • It checks availability live and offers exactly two real open times, then asks if you want a different day if neither fits. On the demo line, that is Crest's own demo calendar.
  • It books the time you pick, then reads the booking back once, in full: day of week, date, spoken time, and your time zone in words. “So that's Tuesday, July fourteenth, at two thirty in the afternoon, Eastern time. Sound right?”
  • “Booked” means verified. The agent only calls a booking confirmed after the system has independently read the new appointment back from the calendar. If the booking fails, it says so plainly and tells you a real human will follow up; it never retries silently and never claims a success it cannot back up.

The text confirmation

Once a booking is verified, the agent asks whether you want the details by text. Say yes and a confirmation lands on your phone, from the demo line, written the way a real business writes to a customer:

Crest Systems
(855) 552-8611
Crest Systems: You're all set. HVAC repair is booked for Tuesday, July 14 at 2:30 PM. We'll see you then — reply here or call us back if anything changes.
Perfect, thanks.
The exact message the product composes from the verified booking. Note the register: the agent speaks in a loose, spoken cadence on the call, but it writes in clean, properly punctuated sentences.

The text is composed from the booking the calendar already read back, never from anything the model types freehand, and it is gated on three simple promises:

  • Only with your consent. A booking does not imply permission to text you; the agent asks first. If you decline, nothing is sent and the appointment still stands.
  • Only to your verified number. The destination is bound to the number your consent covers, so the agent has no way to send your details anywhere else. A misheard number cannot route a confirmation to a stranger.
  • Only announced once it is real. The agent tells you a text was sent only after the carrier confirms it went out. If delivery does not land, it says so on the call instead of pretending.

Hard limits

  • It never collects payment card numbers or other sensitive data; it refuses outright and says why.
  • It never claims to have done something it did not do; every success it reports is backed by a verified tool result.
  • It does no upselling and applies no pressure; a caller who does not want to book is let go warmly.
  • Demo calls are kept to a natural few minutes, and the caller can end the call at any point.
All of this is recorded, and checkable
Every call is recorded and transcribed, and each action the agent takes is written to a log that cannot be edited after the fact. That log is also how these rules get checked against what actually happened, so they are commitments you can verify, not promises you have to take on faith. See Recording & data.
