How TIM4biz catches it

Call records stream from your PBX into TIM4biz in real time. Our rules engine evaluates every call against configurable thresholds and known-risk destinations.

1

Collect

CDRs are ingested from your PBX continuously — on-premise, cloud or hybrid.

2

Evaluate

Rules check for unusual length, volume, cost, international and premium-rate destinations.

3

Alert

Email or SMS notifications fire instantly so you can block extensions or trunks before more damage occurs.

The three components of cybercrime

Toll fraud thrives wherever all three meet. You can't remove the knowledge — it's freely available online. You can shrink the opportunity and detect the motivation early.

  • Knowledge — the same know-how used to operate a PBX day to day is published online.
  • Opportunity — default passwords, poor configuration and unmaintained systems open the door.
  • Motivation — mostly money: cheap calls, reselling access, or premium-rate kickbacks.

Suspicious signals we watch for

Every business is different — thresholds and watch-lists are configurable per extension, department, trunk or time of day.

External

International & premium-rate

Calls to high-cost country codes or 1-900 / premium services outside normal business patterns.

External

Out-of-hours bursts

Spikes in outgoing call volume overnight, weekends or holidays when staff aren't on site.

External

Unusually long calls

Single calls exceeding configured duration thresholds — a classic sign of trunked-out fraud.

Internal

Cost per extension

An extension racking up unexpectedly high call cost in a short window.

Internal

After-hours staff

Cleaners, contractors and night staff making calls outside their normal scope.

Operational

Trunk saturation

All outgoing trunks busy with calls to the same destination — often the first visible symptom.

Frequently asked questions

A few of the questions we hear most when teams first set up toll-fraud alerting.

What is toll fraud, exactly?

Toll fraud is the unauthorized use of a telephone system to place calls at the owner's expense — typically to international destinations or premium-rate numbers that pay kickbacks to the attacker.

How quickly will I know about an incident?

Alerts are delivered as calls are processed — usually within seconds to a few minutes — by email and SMS so the right people can act immediately.

Can I tune the rules for my business?

Yes. Thresholds for duration, cost, destination and volume are configurable per extension, department, trunk, time of day and day of week.

Does this replace PBX hardening?

No — prevention always comes first. Strong passwords, current firmware and a properly configured dial plan reduce the opportunity. TIM4biz adds the detection layer for anything that still slips through.

Which PBXs are supported?

TIM4biz supports 150+ PBX platforms including Cisco, Microsoft, Vodia, 3CX, Mitel, Avaya, NEC and Fonality. See the full PBX support list.
