AI voice agent for Bitrix24

The phone rings. The lead is already in Bitrix24.

A voice agent picks up, asks three short questions, understands the answers and writes a structured lead into your CRM. Nobody on your team touches it.

The browser microphone stands in for the phone line here. The conversation engine, the extraction and the Bitrix24 push are the same code a real call runs.

How it works

Five steps, no human in the loop

Start a test call above and watch each step light up as the call moves through it.

Call

A public phone number receives the call and hands it to the bot.

POST /voice

Speak

A neural voice plays the greeting and the preset questions.

text-to-speech

Listen

The caller answers in a short sentence, which is turned into text.

speech-to-text

Understand

The NLP layer pulls out service, company and contact channel.

structured JSON

Lead

The payload is pushed to Bitrix24 as a new lead, transcript included.

What it understands

Real sentences in, clean fields out

People do not answer like a form. The bot strips the small talk, ignores the option a caller rejects and spells out an email address said aloud. Every pair below is a passing test in the repository.

"We need a new website for our store."
Desired serviceNew website for our store
"My company is called northgate rentals."
Company nameNorthgate Rentals
"I don't like phone calls, so Telegram please."
