Network carriers work with Mobile Analytic Engine Providers (MAEs) to protect their customers from fraudulent and nuisance phone calls. These MAEs monitor and analyze call patterns, user behavior, and complaint data to flag potential spam or scam calls.
Factors include:
- Call Volume & Frequency – High call volumes, especially short-duration or unanswered calls, can trigger a negative label.
- Consumer Feedback & Reports - When recipients frequently report or block a number, it increases the likelihood of a negative tag.
- Call Answer Rates & Behavior – Low answer rates and frequent hang-ups can indicate unwanted calls.
Tagging practices may vary by carrier, the core objective remains the same: to identify and reduce nuisance calls, even when they originate from legitimate businesses.
