The idea
Number is a Melbourne studio that builds AI voice and custom agents. They answer calls, qualify leads and book jobs, wired into the stack you already run.
Agents connect to your existing SIP or PBX, so your number never changes. Every version is tested in a sandbox before it ships, every live call can be monitored or taken over, and past calls fine-tune the next release. We also advise companies scaling agents in-house, with clients in six cities across Australia, the USA, Malaysia and Vietnam.

How it works
We start with the calls you already get: the recordings, the transcripts, the questions your team answers fifty times a day. Every build then runs the same four steps.
We pull your call recordings and map every intent, edge case and handover before any logic is built.
Subflows act as specialised agents, wired over API into your phone system, CRM, calendar and billing.
Simulated callers run every branch in the sandbox. Versions are compared side by side and rolled back in a click.
Live calls are monitored in real time. Your team can whisper, barge in or take over, and past calls fine-tune the next version.
Production ready
Telephony, agents, integrations and monitoring are versioned together. Every change is previewed, compared and reversible before a caller hears it.
One view of every call
Every call, webhook and API, visible as it happens. Debug faster and ship with confidence.

No. We connect to the SIP trunk or PBX you already run. Your number doesn't change, and nothing gets ripped out to make room for the agent.
Voice and messaging such as ElevenLabs, Deepgram, WhatsApp, Telegram, Zoom and Google Meet. CRM and support tools such as HubSpot, Intercom, Zendesk and Help Scout. Ops and data tools such as Google Calendar, Calendly, Airtable, Notion, Supabase, Stripe, Xero, MYOB and Shopify, with n8n, Zapier and Make covering most of the rest.
Yes. Your team can monitor any live call, whisper guidance to the agent, barge in, or take the call over completely.
Every change runs in a sandbox first, against simulated callers. Each version of the agent is tracked, so you can compare versions, run A/B tests and roll back without downtime.
Past calls become training data. Fine-tuning on your own conversations improves accuracy and behaviour, and failed steps are flagged so they're fixed in the next version.
Data is hosted in Australia and handled in line with the Australian Privacy Principles. Outbound calling is built with ACMA rules in mind from the start.
