Full Description
Your customers expect instant, intelligent responses around the clock. An AI-powered voice assistant answers calls, understands natural speech, and handles enquiries without a human agent on standby — reducing missed calls, cutting support costs, and delivering a consistent brand experience every time the phone rings.
Zinn Digital, based in London, builds sophisticated voice call AI assistants using a proven stack: Twilio for telephony, OpenAI for natural language understanding, and AWS for a reliable, scalable backend. Every assistant is custom-built to your specific business requirements — not a generic template dropped into your account.
**What is included across all tiers**
Every engagement begins with scoping your use case so the assistant is configured for the conversations your callers actually have. The core build includes Twilio integration for seamless voice call handling, OpenAI-powered natural language processing so the assistant genuinely understands intent, and an AWS backend that scales with your call volume. Comprehensive testing and deployment support are included before handover, so the assistant is production-ready from day one.
**How it works**
1. You place your order and share your project requirements via the order chat.
2. Zinn Digital reviews your brief and clarifies scope if needed.
3. Development, testing, and quality assurance take place within the agreed timeline.
4. The completed assistant is delivered with deployment support included.
5. Revisions are addressed promptly within the revision allowance for your tier.
**Who is this for?**
This service suits businesses of any size that handle inbound calls and want to automate responses, qualify callers, capture information, or route enquiries intelligently — including service businesses, agencies, SaaS companies, healthcare providers, property firms, and e-commerce operations.
**Why Zinn Digital?**
Zinn Digital specialises in AI-driven automation and is based in London, England. The team works with a focused stack — Twilio, OpenAI, and AWS — meaning deep expertise rather than broad generalism. Every voice assistant is bespoke: built, tested, and deployed to your specification rather than resold from a pre-built template. If your requirements are complex, the Premium tier delivers a full-featured, production-grade solution with extended development time to match.

Frequently Asked Questions
Once you place your order, please share details about your use case — for example, what types of calls the assistant will handle, any specific responses or routing logic required, and any existing systems it needs to connect with. The more context you provide, the faster development can begin. If anything is unclear, we will follow up via the order chat.
The Basic tier suits straightforward setups — a single-purpose assistant with a defined scope that can be built and deployed quickly. The Boost tier is appropriate when your use case involves more complex conversations or additional configuration. The Premium tier is designed for full-featured, production-grade assistants with advanced logic, multi-turn dialogue, and high call-volume requirements.
It is helpful if you have accounts in place, but please raise this in your requirements when you order. We can advise on account setup as part of the onboarding process via the order chat.
Deployment support means the assistant is not simply handed over as code — we assist in getting it live in your environment and confirm it is functioning correctly before the order is closed. The scope of deployment support scales with the tier you choose.
Each tier includes three revision rounds. A revision covers adjustments to the delivered build based on your feedback — for example, changes to conversation flow, response phrasing, or configuration tweaks. New feature requests outside the original brief are not counted as revisions. Additional revision rounds can be purchased as an add-on.
If you require integration with a third-party system, please include those details in your project brief when you order. This will allow us to confirm whether the scope fits your chosen tier or whether an upgrade is more suitable.
You will receive a prompt message via the order chat asking you to confirm your project requirements. Development begins once the brief is clear. You will be kept updated throughout, and the completed assistant will be delivered within the agreed timeframe for your tier.
