Full Description
Your business deserves a phone line that never sleeps, never misses a lead, and never puts a caller on hold indefinitely. That is exactly what a custom AI calling agent delivers — and it is what this service is built to provide.
Whether you need an inbound receptionist that qualifies enquiries and books appointments, or an outbound agent that follows up on leads and handles reminders at scale, this service configures, builds, and deploys a voice AI solution tailored to your specific workflow. You get a fully functional AI agent — not a template, not a demo — ready to handle real calls from day one.
**What Is Included**
Every order begins with a 30-minute consultation to map your use case, call flows, and goals. From there, your agent is configured for either inbound or outbound calling (or both, on higher tiers) and connected to a call transcription portal so every conversation is logged, searchable, and actionable. The agent can manage appointment setting, lead qualification, live call transfers, follow-up sequences, support queries, and FAQ handling — operating around the clock without additional headcount.
The underlying infrastructure supports up to 1,000 simultaneous calls, meaning the solution scales with your ambitions rather than becoming a bottleneck.
**How It Works**
1. You purchase and share your project brief via the order manager.
2. We conduct your 30-minute strategy consultation to define call flows, scripts, and integrations.
3. Your AI agent is built, tested, and delivered with your transcription portal access.
4. You review, request revisions if needed, and go live.
**Who This Is For**
This service suits businesses that rely on telephone communication to generate or service customers — sales teams wanting to automate BDR and SDR outreach, service businesses that book appointments by phone, e-commerce or SaaS companies managing support at scale, and operations teams looking to reduce manual follow-up work without growing headcount.
**Why Zinn Digital**
Based in London, England, Zinn Digital has delivered over 50 successful AI implementations across customer service, sales, marketing, and operations. That track record means your project is handled by a team that has already solved the edge cases, call-flow challenges, and integration complexities that catch less experienced builders off guard. You are not funding a learning curve — you are buying proven execution.
AI calling is no longer an emerging technology reserved for enterprise budgets. It is the operational standard your competitors are already adopting. This service gets you there efficiently, professionally, and without the overhead of hiring, training, or managing additional staff.

Frequently Asked Questions
You will need to share a description of your use case — whether the agent is inbound or outbound, the primary goal (e.g. booking appointments, qualifying leads, handling FAQs), any existing scripts or call flows you use, and details of any tools or CRMs you want the transcription data to feed into. The clearer your brief, the faster we can build.
The consultation is a working session where we map out your call flows, define the agent's objectives, confirm technical requirements, and align on tone and script logic. It ensures what we build is genuinely tailored to your business rather than a generic setup.
The Starter tier covers one direction — inbound or outbound — as defined during your consultation. The Boost and Premium tiers include configuration for both, along with more complex multi-flow logic.
The infrastructure supports up to 1,000 simultaneous calls, so the solution is built to scale with business growth rather than becoming a constraint.
Every call your AI agent handles is automatically transcribed and stored in the portal, giving you a searchable record of conversations, outcomes, and caller data. This is particularly useful for quality review, compliance, and feeding insights back into your sales or support processes.
A revision covers reasonable adjustments to the agent's script, call flow logic, or configuration based on your feedback after delivery. Significant changes to the original brief — such as adding an entirely new use case — may require a separate order or upgraded tier.
No. The agent is delivered as a ready-to-use solution. You will receive access to the transcription portal and guidance on how to monitor and review calls. If you need deeper technical handover notes, the written documentation add-on covers that.
Any business that uses telephone communication to generate, qualify, or service customers will benefit. Common examples include healthcare and clinic appointment booking, real estate lead qualification, SaaS and e-commerce customer support, and sales teams running outbound prospecting campaigns.
