How many calls per day before being flagged as spam?
The exclusive Huhu bureau investigation into telecom detection algorithms.
The 6 Trigger Signals
What carriers actually monitor
1. Raw Volume
The total number of calls over a 24-hour window. The most basic signal.
2. Answer Rate
Answered/failed ratio. Below 15%, you are flagged as harmful.
3. Reports
The pointing finger. "Report as Spam" clicks on mobile devices.
4. Average Duration
Calls under 10 seconds in a row scream "Automated Calls".
5. Hourly Pace
Concentrated bursts are more suspicious than a steady flow.
6. In/Out Ratio
A number that only calls out without ever receiving is an easy target.
Comparison by Sector

Sensitive Sector
Insurance, Real Estate, BPO.
Toxic Sector
