π Understanding Caller ID Reputation & Spam Labeling
Phone carriers like AT&T, Verizon, T-Mobile, and Sprint use call analytics to flag potential spam calls. These analytics take into account:
π How calls are flagged as spam:
β
Call Frequency β Too many outbound calls in a short period
β
Consumer Reports β Users marking numbers as spam
β
Call Answer Rates β Low pickup rates signal potential robocalls
β
History & Complaints β Past reports & call behavior
Even legitimate businesses can be mistakenly flagged as spam! Shape helps reduce these risks through compliant call routing and reputation management tools.

π« Why Are My Calls Being Flagged as Spam?

π Displaying a Caller Name (CNAM) in Shape
πΉ When you add a caller name via Shapeβs "Manage Phone Settings", itβs registered in the CNAM database.
π Key Facts About CNAM:
β Takes up to 72 hours to update
β Carriers update their CNAM registries periodically
