'Spam Likely' label: what it means in pay per call

'Spam Likely' label: A warning that carriers and phone apps show on calls from numbers their analytics flag as likely spam or scam.

How it works in pay per call

Labels come from carrier analytics engines (Hiya, First Orion and TNS power many of them) based on call volume, short calls, complaints and other signals. A flagged number can lose a large share of its answer rate.

Fixes include registering numbers with the analytics engines (Free Caller Registry covers several), monitoring reputation, rotating fewer numbers more carefully, and branded calling.

Example

Example: a center dialing 2,000 short calls a day from one local number sees it flagged within days. Registering the number, lowering volume per number and branding the calls can help bring the answer rate back.
