Portfolio / AI voice agents
The phone keeps ringing when nobody's there.
In most businesses the call nobody answers does not come back: it goes to a competitor. TomAnswer puts a voice agent on that call — inbound or outbound — to understand what the caller wants, resolve what it can, book when it should, and hand the phone to a person when it must. We built the platform: the voice through ElevenLabs, the logic in n8n, and the CRM where every conversation lands as data.
01The brief
Answering the phone is a fixed cost.
Answering calls costs the same on a dead Tuesday as on a campaign Monday: someone has to sit there in case it rings. When it rings too much, there aren't enough of them; when it rings too little, you pay anyway. In between, after-hours calls are lost, leads get qualified by whoever picked up, and half of what was said never reaches the CRM.
The brief was to build the platform that absorbs that work: one voice agent per company, with its own script and tone, able to hold a real conversation, decide during the call, and leave the outcome written where the sales team already works.
What a call without a system loses
- 01The one that comes in after hours
- 02The one that comes in during another call
- 03The criteria the lead was qualified by
- 04What was promised and never noted
- 05The appointment booked on paper
- 06The follow-up nobody triggered
Our role
Architecture and build of the platform: conversation flow design, voice integration, decision orchestration, connection to the CRM and the database where every call is stored, plus the product site.
02Architecture
Three things an agent has to get right.
A synthetic voice that sounds great and resolves nothing is an expensive answering machine. The product is won inside the conversation.
A voice that doesn't grate.
Hyper-real synthesis through ElevenLabs, with tone and pace tuned per industry: answering for a clinic is not answering for a workshop. If the voice sounds like a robot, the call is lost in the first second.
The script has branches.
Each company brings its rules — what gets answered, what gets booked, what gets escalated — and those rules live in n8n flows, not in the prompt. Changing a commercial condition is editing a node, not retraining an agent.
The call ends in the CRM.
Contact created or updated, pipeline stage moved, a note with what was said, and the right campaign fired. If the conversation leaves no trace, the call was worth as much as not answering.
03The idea
What this platform had to settle.
A call isn't measured by how it sounds, but by what it writes down.
A voice agent demo always impresses: it speaks well, it understands, it answers. The problem shows up a week later, when the sales team asks what happened with Tuesday's forty calls and nobody can say.
So the system was designed from the end backwards: every conversation has to finish in a state — resolved, qualified lead, appointment booked, or handed off — and that state has to land in the CRM with its note and its follow-up. The voice is the interface; the data is the product.

04The system
From the call to the record in the CRM.
Five pieces and one call crossing all of them in real time, without anyone on the team picking up.

- 01
The call comes in
The agent answers on the first ring, at any hour, and opens with that company's script: name, service, and the question that starts the conversation.
- 02
Listen and understand
The conversation is open, not a menu of options. The caller says it their way and the agent extracts what matters: what they need, by when, and who they are.
- 03
Look things up
Mid-call, the flow can check the database — whether the contact exists, what was promised before, what availability there is — before answering.
- 04
Decide
Business rules run in n8n: resolve, quote, book or escalate. The decision does not depend on the agent's mood or the day of the week.
- 05
Book or hand off
Where there is intent, the appointment goes into the client's calendar. Where the conversation leaves the script, it transfers to a person with the context already gathered.
- 06
Write to the CRM
Contact created or updated, stage moved, a note with the summary, and call tags. The sales team finds a case, not a duration log.
- 07
Fire the follow-up
SMS or email confirmation, appointment reminder, or a recovery sequence if it stayed lukewarm: the campaign leaves from the same CRM, with no manual step.
- 08
Leave the evidence
Transcript, duration, outcome and metrics are stored. That is what lets you audit the agent and tune the script with data instead of impressions.

05Operations
What changes when the agent answers.
The value is not in replacing anyone: it is in the phone no longer being a bottleneck with opening hours.
24/7, no shifts.
The eleven-at-night call gets the same attention as the ten-in-the-morning one, and ten simultaneous calls do not queue: each gets its own agent.
The same criteria, always.
Lead qualification follows the same questions and thresholds on every call. What used to depend on who picked up is now a rule.
One agent per company.
Each client brings its script, its voice and its rules onto the same platform. Adding a company means configuring an agent, not standing up a new operation.

An agent has no screen.
- AgentGood afternoon, this is the assistant at Clínica Norte. How can I help?
- CallerI wanted to know if you have appointments this week, and what an assessment costs.
- AgentWe do — Thursday and Friday are open. The assessment is one hundred and twenty thousand pesos and includes the diagnosis. Would Thursday at three work?
- CallerThursday is fine. My name is Andrea Ruiz.
- AgentDone, Andrea: Thursday at three. Your confirmation arrives by text within a minute.
A reconstruction of what happens while it rings: the agent greets, catches the intent, checks availability and books, while the flow lights up its decisions. The dialogue is invented — real calls are clients' conversations and are not published.

Of the day's thirty-four calls, three left the script and went to a person with the context already gathered. None went unanswered, including the one at eleven at night.
The board the system leaves behind: how many calls came in, how many ended as a lead or an appointment, and which ones went to a person. The accounts are invented: no client company's real operation is published.
The header of tomanswer.com, where the brand — a sound-wave mark on a dark ground — states the proposition and opens sign-up.
10The outcome
The phone stopped being a shift.
What was delivered is a platform, not a demo: the agent answers, holds the conversation, decides on the business's rules, books where there is intent, hands off where the script ends, and leaves every call written in the CRM with its summary and its follow-up. What used to depend on someone being at a desk now happens at any hour.
And it grows by configuration: each client company arrives with its script, its voice and its rules on the same architecture. Adding a client means standing up an agent, not standing up a call centre.

About what is shown
The call dialogue and the dashboard figures are invented. Real conversations belong to the customers of the companies running the platform: publishing them would expose third-party data — and a demo is not worth what evidence that the system leaves a record is worth.
More work
If the missed call is your most expensive cost, it is also the easiest to remove.
A voice agent does not replace your team: it takes the repetitive half of the phone off them — hours, prices, availability, qualification — and hands back, in writing, the part that actually needs a person. It can be built on the CRM you already use.
