24/7 inbound coverage. No missed calls. No receptionist cost.

AI voice agents that qualify inbound callers, book appointments, and screen applicants, indistinguishable from a trained human agent, available every hour of every day.

§01, When this fits

Calls are missed, leads drop off, and your team is answering questions a system could handle.

Every business with inbound call volume faces the same maths: a human receptionist costs £25–40K per year, works business hours only, handles one call at a time, and goes on holiday. The result is missed calls, dropped leads, and specialist time spent on qualification questions.

We build voice agents that handle inbound calls end-to-end, with natural conversation, real-time calendar access, CRM integration, and hand-off logic for calls that need a human. Deployed via Vapi, with ElevenLabs voice synthesis. Live in under a week.

Without it

Calls go to voicemail outside business hours. Specialists spend 20+ hours/week on inbound qualification. Leads drop if not called back within minutes.

With it

Every call answered 24/7. Caller qualified, appointment booked, CRM updated, automatically. Specialist only receives hand-offs that need human judgement.

The approach

How we build it.

Every stage has a defined role and a quality gate before the next one runs, the same engineering spine under every Agentix system.

    Use Case Scoping

    We map every call type, qualification question, booking flow, and hand-off trigger. This defines the conversation design and integration requirements.

  2. 02

    Conversation Design

    All call flows, objection handling, and disambiguation scripts written and reviewed. The agent knows when to press, when to offer alternatives, and when to hand off.

  3. 03

    Voice Configuration

    Vapi agent configured with your chosen ElevenLabs voice. Latency optimised, target under 400ms response time for natural conversation rhythm.

  4. 04

    Integration

    Calendar API for live slot availability. CRM webhook to update contact records after every call. n8n automation for any post-call actions.

  5. 05

    Test & Refine

    50+ call scenario tests before live deployment. Edge cases: caller confusion, unusual requests, unhappy paths all tested and handled.

  6. 06

    Deploy & Monitor

    Live in 2–5 days from scoping sign-off. Call recordings and transcripts available. Performance monitored on qualification rate and booking conversion.
