Vicidial paved the way.
Vicidial paved the way.
We walked the whole road.
Vicidial is good software and gave the industry a standard for years. But NeervoX is not built on top of it and does not consume its API: the engine is built in-house, end to end. That changes one thing, which changes everything: when your operation needs something different, we build it.
Built on someone else
- What you can change ends where the API ends.
- Every update of the base project can break your customizations.
- A requirement outside the mold ends in "it cannot be done".
NeervoX
- The code is ours: it adapts as far as your operation asks.
- No third-party dependencies deciding your roadmap.
- What does not exist today gets built tomorrow.
Built in
Your agents do not talk
Your agents do not talk
to answering machines
NeervoX comes natively connected to NeerBat, our AI voicemail detector. It listens to the call the moment they answer and, if there is a recording on the other side, discards it before it reaches the agent. This is not an after-the-fact report: the call never comes in.
Tells a person from a recording in seconds
Also detects powered off, non-existent and suspended
Every verdict is logged in the customer record
Every answering machine an agent listens to is paid time that produces nothing. With NeerBat that time goes back into the queue of real calls, and the number flagged as dead stops being dialed.

Use us as the engine
There is no need to change what already works. NeervoX can be used only as a channel engine —voice, WhatsApp, SMS— underneath the CRM your team already knows. Your system says who to call; we dial, detect voicemail, record and hand the result back.
You ask us to
- Load a dialing list
- Call a number now (click-to-call)
- Send WhatsApp or SMS
- Launch a mass voice campaign
We hand back
- Real-time call status
- Voicemail detector verdict
- Recording and real duration
- Outcome of the agent interaction
The engine
The whole call cycle, in one place
From building the list to the agent dispositioning the result. No spreadsheets in between and no systems that do not talk to each other.
Smart lists
Generator with contact-probability scoring, best hour per number and automatic exclusions: active promises, blocks, dead lines and legal quotas.
Live monitoring
Every agent status by the second, with listen, whisper and barge-in on the call. Plus the live agent screen when you need to coach closely.
Recordings with retention
Every call is recorded and kept for as long as the law requires, with a two-year minimum the system will not let you lower through configuration.
Mass voice IVR
Broadcast campaigns with an options tree and transfer to the agent. The robot filters and hands over only those who asked to talk to someone.
Reports that add up
Contact rate, occupancy, abandonment and recovery measured against the actual phone system records, not against estimates.
Omnichannel
One conversation that changes medium,
not four separate conversations
The customer replies on WhatsApp to the call they did not answer. The agent sees the whole thread in the same record, no matter where each message came in.
Voice
WhatsApp
SMS
Chat
Email
Mass voice
A robot that filters,
and agents who only talk to interested people
Instead of twenty people calling a thousand, the robot calls the thousand and transfers only those who pressed a key. The rest never occupy an agent at all.
1 · The robot dials
The campaign goes out at the pace you set, respecting hours and holidays.
2 · Discards what is useless
NeerBat detects the answering machine and hangs up: nobody wastes audio on a voicemail.
3 · Plays your message
The audio you recorded, with your campaign voice and script.
4 · The person chooses
And the tree decides what to do with each answer.
1 Talk to an agent
2 Leave their details
9 Do not call again
5 · Transfers to the agent
The call comes in with the customer record already open on screen.
- It stops on its own if nobody is available. If every agent is busy, the robot stops dialing instead of leaving people waiting.
- End time and holidays. The campaign shuts down by itself at the hour you set, and does not run on holidays.
- Opt-out during the call. Anyone pressing the "do not call again" key is out instantly, without going through an agent.
- Data capture without an agent. A node can log the interested person to be called back later, even if nobody is free now.
- You know where people drop off. The report shows how many heard the full audio, which key each one pressed and at what point in the tree the call dropped.

Compliance
Compliance lives in the engine,
not in a manual
In collections, the rules are not a recommendation. NeervoX applies them before dialing: if a call is not allowed, it does not go out.
Hours and holidays
Legal contact window and the local holiday calendar applied by the dialer itself, not by operator discipline.
Contact quotas
The attempt limit per debtor is counted across every channel: calls, SMS and WhatsApp share the same quota.
Do not disturb
When someone asks not to be contacted, they are out of every list instantly and permanently.
Use cases
One engine, three ways to use it
Not every operation needs the same thing. NeervoX starts where you are today and grows when you need it, without switching systems.
Recover your portfolio
Debtor management with the legal rules applied by the engine itself, before dialing.
- Debtor record and payment promises
- Contact quotas shared across channels
- Legal hours and local holidays
- Recovery measured against the phone system
Sell more with the same headcount
The dialer hands over only calls answered by a person, so the agent talks instead of waiting.
- Lists prioritized by contact probability
- Predictive dialing with abandonment control
- Follow-up and call rescheduling
- Conversion reports per agent
Just dial, no CRM
If you already have your management system, use NeervoX only as the dialing engine.
- Five modes, from preview to pure predictive
- Integration with your system through the API
- Recordings and reports included
- Without migrating the data you already have
Tech specs
What is underneath
Our own infrastructure and numbers measured in real operation, not brochure estimates.
Phone system
PJSIP technology on our own Asterisk. Our own SIP trunks, with the carriers you choose and several in parallel.
Capacity per server
100 concurrent agents per server, measured under real load. To grow you add servers, you do not change systems.
Agent phone
Webphone in the browser. Nothing to install on the computer.
Recordings
Every call recorded, with a two-year minimum the system will not let you lower.
Monitoring
Live listen, whisper and barge-in, plus the agent screen.
Voicemail detection
NeerBat built in: it discards answering machines, powered-off and non-existent numbers before they reach the agent.
Reports
Measured against the phone system records, not the CRM database. And custom-built: if your client asks for their own format, we build it.
Integration
NeervoX underneath the CRM
you already use
Some operations already have their system and will not change it, and that is fine. For those, NeervoX does not compete with your CRM: it connects underneath and lends it the channels it lacks.
Dialing
Load lists, launch campaigns, dial a specific number from your record, and control the live call: hold, transfer and conference.
Messaging
WhatsApp and SMS with templates, individual or bulk sending, and delivery status back. The legal quota is respected just like on voice.
Live events
Your system subscribes and receives every change instantly: the call was answered, the detector said voicemail, the agent dispositioned it. Without polling every five seconds.
Interactions and results
Everything the agent logged comes back to your CRM: disposition, sale amount, payment promise, recording and the real conversation length.
Authentication
Token-based access with role permissions. Inbound webhooks validate signatures, and every API call is logged.
Missing something?
The code is ours. If your integration needs an endpoint that does not exist today, we build it. We do not depend on a third party roadmap.
# Dial a number from your own CRM POST /api/telephony/click-to-call { "numero": "56912345678", "agent": "1004" } # And your system receives the result live EVENT call:state → answered / voicemail / no answer EVENT call:event → recording, duration, disposition
Full documentation is delivered during the technical stage, with a sandbox so your team can integrate without touching production.

Frequently asked questions
What people ask us before starting
Is there a free trial?
Yes, 2 weeks at no cost, no credit card and no contract. It includes the support to get the dialer configured with your trunks and your campaigns: we do not leave you alone with a username and a password. If it does not work for you at the end, nothing happens.
Is it for sales or only for collections?
Both. The dialing engine is the same; what changes are the rules and the customer record. In sales the collections frequency limits do not apply, and the system tells them apart on its own based on the campaign type.
Do I have to change my phone system?
Not necessarily. NeervoX brings its own phone system, but it can work with the SIP trunks of the carrier you already have.
What does the agent computer need?
A browser and a headset. The phone runs inside the page, so there is nothing to install and no devices to configure at each desk.
How is it charged?
Per connected agent, with phone traffic billed separately by your carrier. We work out the details based on the size of your operation.
Can I take my data if I leave?
Yes. The lists, the results and the recordings are yours and are exported whenever you ask.
Does it meet collections regulations?
Legal hours, holidays, contact quotas and the do-not-contact register are applied inside the engine: if a call is not allowed, it does not go out. The minimum recording retention cannot be lowered through configuration either.
Who we work with
Telephony backed by real carriers
The dialer is only one part: without stable trunks no operation works. We work with established SIP providers so call quality does not come down to luck.
