Sentry's Digital Voice service deploys AI voice agents that answer inbound and make outbound calls around the clock, and take real actions mid-conversation — booking, updating the CRM, taking payment — while the customer is still on the line.

AI voice agents that handle inbound and outbound calls and take real actions live, mid-conversation. Real-time speech, an agentic reasoning layer, and execution across your stack — while the customer is still on the line.

## What it does

AI voice agents that handle inbound and outbound calls and take real actions — booking, updating the CRM, taking payment — live, mid-conversation.

## Where it creates value

The response-and-conversion stage at the speed of the call: it removes the hours-to-days gap between intent and action, converting and serving on 100% of calls, each tied to a named owner.

## Why it cannot be ignored

Every unanswered call and slow callback is a customer handed to a faster competitor. Speed-to-lead decides who wins the deal — a missed-call business is quietly losing the very enquiries it paid to generate.

## What you get

- **Inbound & outbound, 24/7** — Inbound support and outbound qualification, booking, renewals and after-hours cover — day or night.
- **Acts mid-conversation** — Books, subscribes, updates the CRM and charges while the customer is still on the line — zero handoffs.
- **Every call accountable** — Transcribed, scored against SLAs and tied to a named owner — measured on 100% of calls, not a 2% sample.

## Key concepts

- **Retell AI** — A voice AI platform that runs the real-time speech layer of a call — listening, speaking, and holding the turn-taking close enough to natural that people stop noticing it. Retell AI is one of the voice platforms we build on inside Digital Voice. We select and run it as part of the managed service rather than selling it on its own, so you get the outcome without owning the integration.
- **Speech-to-speech latency** — The gap between a caller finishing a sentence and the agent starting to reply. Past about a second, callers talk over the agent and the conversation stops feeling human. It is the single number that decides whether a voice agent is usable.
- **Mid-call actions** — The agent calling your systems while the caller is still on the line — booking, updating the CRM, taking payment. Without it a voice agent is an answering machine with better grammar. With it, the call ends with the work already done.

## Questions and answers

### What can an AI voice agent actually do on a call?

It books appointments, sets up subscriptions, updates your CRM and takes payment while the customer is still on the line. That is the distinction that matters: the agent completes the task during the call rather than capturing a message for someone to action later, so there is no handoff to be lost.

### Will callers know they are speaking to an AI?

They are speaking to real-time synthesised speech with an agentic reasoning layer behind it, so the conversation flows naturally rather than following a phone-tree script. Sentry treats how that is disclosed as your decision, set with you when the agent is configured rather than assumed.

### What happens to the calls we currently miss?

They stop being missed. Every unanswered call and slow callback is a customer handed to a faster competitor, and speed-to-lead decides who wins the deal. A missed-call business is quietly losing the enquiries it already paid to generate — AI voice agents cover inbound, out-of-hours and overflow so nothing rings out.

### How do we know the agent is handling calls properly?

Every call is transcribed, scored against agreed SLAs and tied to a named owner. That is 100% of calls rather than the 2% sample a human QA process manages, so a drift in quality shows up in the measurement rather than in a complaint months later.

### Is this for inbound support or outbound sales?

Both. Inbound covers support, enquiries and after-hours cover; outbound covers qualification, booking and renewals. They run as one service because the same reasoning layer and the same CRM integration serve both directions.

### What does a managed voice agent service cost?

Sentry's managed services start at £3,000 per month, scoped to the work, with third-party tool costs for the services we manage included up to a fair-use cap; paid advertising spend is excluded. It begins with a free Discovery session and a Financial Value Model, which for voice usually means quantifying what your missed and slow-answered calls are currently costing before anything is deployed.
