Voice agents for business

Every call answered. Every follow-up sent.

Voice OS puts AI agents on your own phone numbers. They pick up, speak naturally, book the appointment, qualify the lead and send the WhatsApp follow-up — then show you exactly what happened on every call.

How it works

On the phone this week, not next quarter.

Connect a number

Point a number from your carrier at Voice OS. Inbound calls ring your agent; outbound campaigns dial from it.

Give the agent a job

Install a ready-made app — Booking, CRM, Sales, Real estate, Recruiting — or write your own instructions, knowledge and call flow.

See every call

Transcripts, recordings, outcomes and a quality score on every conversation — with suggestions for what to change.

Use cases

An agent that already knows the job.

Each app sets up its agent, the tools it needs and a dashboard for the work it produces — the diary, the pipeline, the shortlist.

Booking

For clinics, salons, studios and service businesses.

Offers free slots and books them
Moves and cancels without a reference number
Mirrors to Google Calendar with a meeting link

CRM

For teams that need every caller qualified.

Captures who called and what they want
Files each lead at a stage
Works with Salesforce and HubSpot once connected

Sales

For teams selling out, not just answering in.

Works a campaign list inside calling hours
Keeps value, next step and close date current
Books the demo, rings back when asked

Real estate

For agencies with more enquiries than negotiators.

Answers questions from your own listings — never invents one
Books viewings into the diary
Records budget, area and must-haves

Recruiting

For hiring teams screening at volume.

Runs a structured first screen against the role
Asks notice period and salary, gives an honest verdict
Books the interview with the hiring manager

Platform

Everything a call touches, in one place.

Natural conversation

Realtime speech, or choose your own speech, language model and voice — OpenAI, Deepgram, Cartesia, ElevenLabs, Sarvam.

Knowledge base

Answers from your own documents, prices and policies instead of guessing.

Call flows

Draw the conversation step by step, branch on what the caller says, and hand off to a person.

Campaigns

Upload a list and let the agent work it inside your calling hours, with callbacks when people ask.

Remembers callers

Recognises a returning number and picks up where the last call left off.

WhatsApp and web chat

The same agent follows up on WhatsApp and answers on your website.

Quality on every call

Each conversation is scored against your criteria, with concrete changes to the agent suggested.

Your brand

Put your own name, logo and colours on the console your team and customers use.

Developers

Everything in the console is in the API.

Build agents, flows and voices from code, place calls, and get a webhook when each one ends — with the transcript, the outcome and what the agent did.

API keys scoped per workspace
Webhooks signed so you can trust them
An OpenAPI spec for every endpoint
