TrustCall API

TrustCall provides real-time phone number reputation monitoring, including spam scores from major carriers, app scores, and FTC complaints.

What is TrustCall?

TrustCall monitors your outbound phone numbers to detect:
  • Carrier spam flags - When carriers label your number as spam/scam
  • App blocking - When apps like RoboKiller or Nomorobo flag your number
  • FTC complaints - Consumer complaints filed against your number

Why Monitor Your Numbers?

If your outbound numbers are flagged as spam, your calls won’t connect - leading to lost business and wasted dialing costs.
Proactive monitoring helps you:
  • Identify flagged numbers before they impact your business
  • Take corrective action quickly
  • Maintain high connection rates
