The phone channel has changed.

Carriers and call-blocking apps now use dynamic reputation scoring, not just caller authentication, to decide whether a call is delivered, labeled, or blocked. 

Even compliant businesses are frequently mislabeled as Spam, Scam, or Fraud, often without knowing it’s happening. 

STIR/SHAKEN authenticates calls. It does NOT prevent spam labeling.

Reality Check: Most businesses don’t know this is happening

  • Calls can be labeled differently across carriers 
  • One outbound number may be healthy while another is silently flagged 
  • There are no alerts when reputation changes 
  • Answer rates drop before anyone knows why 
 

By the time complaints surface, revenue has already been impacted. 

When calls don’t connect, revenue doesn’t either.

  • Lower answer and connection rates 
  • Missed sales, renewals, and appointments 
  • “My calls show spam” support escalations 
  • Brand trust and customer confidence erosion 
  • Wasted agent time and outbound spend
