A call that went to voicemail
Nobody was free.
Twilio AI voice agent for businesses that miss calls while they are busy
ConversationRelay turns the caller's speech into text and streams it to your application over a WebSocket, then reads your reply back in a voice you choose, so the model sees text while Twilio handles recognition and synthesis. BoldBellows records the caller's number, the call SID and the agent version before the first word is spoken, streams the conversation over the relay and falls back to voicemail or a person the moment the agent is unsure, then greets the caller with a recording notice, understands the request, answers from approved information, books or routes the call, confirms back what was agreed, and transfers to a named person the moment the caller asks for one or the agent is not sure. A short summary and the outcome are saved against the call.
From $1,580, paid once. Automate Twilio inbound calls.
B2Before and after
A small business misses a quarter of its calls and does not know which. The voicemail box fills, the caller who wanted a quote has gone to a competitor by the time anyone listens, and the one who wanted to reschedule just hangs up. A phone menu is the other extreme: press one, press two, press zero, and the person who wanted an answer gets a maze. A voice agent that rambles or invents answers is worse, because the caller cannot see what was promised.

D4How it works
Qualify first, match second, write last; that order is what stops duplicates.
The incoming event is checked for authenticity, its identifiers are recorded, and the route decides whether the Twilio event qualifies.
The call is answered, the recording notice is played, and the caller's speech is streamed as text.
The request is handled or routed, what was agreed is confirmed back, and a person takes over on request.
E5Inside your workflow
On this Twilio AI Voice Agent service, three layers, in order: Capture for eligibility and identity, Coordinate for the proposal itself, Audit for drift and exceptions.
Capture
Applies the in-scope list to every Twilio event, so the AI workflow sees only what you approved.
Capture
Keeps the evidence behind each suggestion next to the Twilio object it concerns.
Capture
Drops, masks or transforms each Twilio value according to the rule written beside it.
Coordinate
Understands the caller, answers from approved information and books or routes.
Coordinate
Matches each event to its proposal by one key built from the caller's number, the call SID, the agent version and the model run and flags the ones it cannot place.
Coordinate
Decides what the agent handles, what it transfers and to whom.
Audit
Holds every difference between Twilio and the AI workflow with its age and its owner.
Audit
Watches response time and moves a slow call to a person.
Audit
Offers a safe next action for each stuck proposal instead of a blind retry, for this Twilio AI Voice Agent service.

I9Your options
Each can answer a call. Only one finishes routine requests, announces recording and transfers on request.
| How a call starts | A voicemail box | A generic voice bot | Our relay-based voice agent |
|---|---|---|---|
| What starts the work | Staff notice and act | The first matching notification | Events inside the agreed scope only |
| How identity is decided | A person recalls the customer | Nothing stored, so nothing to compare | One key: caller number, call SID, agent version and model run |
| What reaches the AI workflow | A partial copy | One object, no relationships | A finished request or a warm transfer, with a saved summary |
| After an uncertain result | A manual clean-up later | It repeats the write | Compares what exists with what was intended |
In the Twilio AI Voice Agent service, when an older event shows up after a newer one, the route notes it and leaves the confirmed proposal alone.
The agent says it did not catch that, offers to transfer, the caller is connected to a person with the summary so far, and nothing is guessed. The existing proposal, if any, is found by one key built from the caller's number, the call SID, the agent version and the model run and judged against the payload before the route decides what to do.
The first design choice is one key built from the caller's number, the call SID, the agent version and the model run; identity, replay and repair all follow from it.

J11The process
The route is built in six steps, and nothing moves on until the last one is signed.
We list why people call, what the agent may answer and when a person must take over.
We arrange narrow Twilio access, confirm the model provider and its data terms, and settle how decisions are identified.
The greeting, the recording notice, what the agent may promise and the transfer rules are written out and approved first.
With Twilio AI Voice Agent in place, each failure path, from a lost reply to a rejected value, is exercised in a test the AI workflow before the live switch.
We launch at a checkpoint, watch the first runs with you, and deliver the written handover.
Questions about how the route behaves in production are answered during the launch window, and the notes are updated.
K12Turnaround
The schedule starts when Twilio access and the approvers are confirmed.
6 to 10 business days
10 to 16 business days
16 to 24 business days
L13Getting started
M14Safety and ownership
Access is limited to the Twilio objects in scope, the model gets a minimised view, and a person approves what changes anything.
Twilio and the AI workflow keep their own code and settings; the route sits between them and uses only what each platform documents.
The integration user or token carries only the rights the route requires.
The mapping names every field that travels. Additions are agreed in writing, not picked up automatically.
The route never resends on hope. It checks the AI workflow for the proposal through one key built from the caller's number, the call SID, the agent version and the model run and decides from what it finds.
Log lines name the record and the result; they do not reproduce the record.
You are not tied to us: the configuration sits in your accounts.

We get thousands of comments and messages every week. BoldBellows built an AI system that replies instantly, filters spam and surfaces the important ones.

P16FAQ
Before you commit, here is what buyers most often want confirmed.
Need only every inbound call answered, with the routine ones finished on the line? A zap handles that. It stops short of the work to answer in a natural voice, transfer to a person on request or keep a record of what the caller was told. That missing layer is what you are paying for.
ConversationRelay converts speech to text and streams it to your application.
Yes, on request or whenever the agent is unsure.
Only if you choose, and a notice plays at the start. Your counsel confirms the wording.
It says so and transfers, rather than guess.
Yes, it can offer and confirm slots against the calendar you name.
A short summary, the outcome and the follow-up, saved to your records.
Yes. Nothing from Twilio reaches the model unless it is on the approved list, and nothing is written back unless it is on the write list.
Yes. Qualification rules, proposal types and approvers are all set to your process, from $1,580.
We document each dependency. When a platform alters something, only the records touching it pause, and you are told which. Fixes beyond the review period are priced on their own. It is also the answer to custom twilio ai voice agent automation.
Q17Answer every call, finish the easy ones and transfer the rest
The Twilio AI route is quoted first, from $1,580.
