Features

Everything a call needs, in one place

An agent needs a number to answer, facts to answer with, systems to act on and somewhere to file the result. All of it is here.

Build an agent in minutes

Write what it should say, pick a model and a voice, and talk to it in the browser on the same screen. No deploy step between an edit and hearing it.

Give it a real phone number

Connect a number from Twilio, Telnyx, Plivo, Vonage or Exotel and point it at an agent. It takes calls in and places them out.

Call a whole list at once

Import your contacts, build a campaign and let it dial. Every number attempted, every answer recorded, progress you can watch as it runs.

Decide what to collect

Build a capture form of the fields you actually need. Agents fill it in from the conversation instead of you retyping notes.

Let it use your systems

Agents call your own APIs mid-conversation to look up an order, check availability or book a slot, then say the answer out loud.

Teach it what you know

Upload your documents and the agent retrieves from them while the caller is still on the line, instead of guessing.

After the call

Every call writes itself up

Nobody replays a recording. The transcript, summary, intent, sentiment and outcome are recorded as soon as the call ends.

Transcript
Thanks for calling. How can I help?
I’d like to book an appointment for Thursday.
Outcomes

Know how each call ended

Resolved, booked, missed or escalated, with the cost and reply speed of every call beside it.

How it works

Live in three steps

There is no deployment between an edit and hearing the result.

  1. 1

    Describe the job

    Tell the agent who it is talking to and what it should get done. Plain sentences, not a flowchart.

  2. 2

    Connect a number

    Point a phone number at it, or skip that and test straight from your browser with your microphone.

  3. 3

    Watch it work

    Every call arrives transcribed, summarised and scored, with the outcome recorded against the contact.

FAQ

Questions, answered

Can it answer a real phone number?

Yes. Bring a number from Twilio, Telnyx, Plivo, Vonage or Exotel, point its voice webhook at NaxCall and assign it to an agent. The agent then handles inbound calls and can place outbound ones.

Can I interrupt it mid-sentence?

Yes. Agents support barge-in, so talking over one stops it speaking and it listens, the way a person would. That is on by default in the browser and on the phone.

What happens to my call recordings and transcripts?

NaxCall is self-hosted. Calls, transcripts and contacts are written to a database on your own machine, and your provider keys stay in your environment file rather than the database or the dashboard.

Do I need to write code?

Not to build an agent, connect a number, upload knowledge or run a campaign. You write code only when you want an agent to call your own API as a tool, and that is a URL and a schema rather than a deployment.

How do I connect it to my own app?

Generate a developer key in settings and call the API with it. The same endpoints the dashboard uses are available to you.

What does a call cost?

Your plan covers voice minutes. On top of that the dashboard records the model cost of every call to six decimal places, so you can see what a conversation actually cost rather than estimating it.

Put an agent on your phone line

Talk to your agent in the browser before you connect a number. The free plan includes 100 minutes.
