VICALL
On-device call fraud detection

Fraud detection built into the call.

An add-on to your phone system, or an app on your iPhone. It listens on the device and flags a fake voice or a fraudulent request while the line is still open.

Choose your setup

Two plugins.

No phone swap, no new carrier, no change to how anyone answers. Detection runs on the iPhone or customer-hosted Vicall Edge runtime, and Vicall stores no call recordings.

on the phone system
A plug-in that sits beside your PBX and scores every inbound call.

A small VM on the same network, joined as a SIP participant. Stood up in an afternoon, no downtime, no porting.

on the handset
An app on the iPhone already in the pocket.

It keeps the familiar calling experience and runs detection on the phone’s own Neural Engine. Deploy directly or through MDM.

Two detection layers.

Both run in the same place the call does: on the handset’s own neural core, or on the customer-hosted runtime beside your PBX. Vicall does not retain recordings or transcripts.

voice clone detection
We hear what a person can’t.

A few seconds of clean speech is enough to clone anyone. The artefacts a synthesiser leaves behind are still there, under a voice that sounds right.

social engineering
Most fraud calls use no clone at all.

A real person simply asks for something a normal call never asks for. The tell is in the words, not the voice.

“Our banking details have changed”
“It has to go out before close”
“Don’t loop in anyone else yet”
“Read me the code that just came through”
urgency paired with secrecy
privacy first

Runs on your hardware.

Cloud-first detection can create avoidable privacy and compliance exposure. Vicall keeps model inference on the iPhone or inside the environment you control.

on device
Scoring happens on the handset, or on a machine inside your own network.
two installs
An app on the iPhone, or a plug-in inside your PBX.
no carrier change
Add protection without replacing the phone system people already know.

Thirty minutes. We look at what you run, say which plug-in fits, and tell you if it doesn’t.
