Troubleshooting calls not reaching business line

In some cases, calls not being routed to a business may be due to Error Code 32017. This occurs when intermediary carrier analytics identify the Caller ID (telephone number) as having a poor reputation, leading to it being blocked.

Explanation of the Issue

Carrier analytics use various metrics to determine the reputation of a telephone number. When a number is flagged with a poor reputation score, calls originating from it may be blocked to protect end users. A low reputation score may result from:

  • Low Answer Rates: A high percentage of unanswered calls can indicate that recipients do not recognize or trust the number.
  • Short Call Durations: Calls frequently disconnected after a short duration can suggest a negative user experience.
  • Unwanted Call Volume: Large volumes of calls perceived as spam or nuisance calls contribute to a negative reputation.

Solution

To resolve this issue and improve the reputation of your telephone number Register the Number with Analytics Providers

  • To register numbers with major mobile carrier analytics providers, visit Free Caller Registry. This site consolidates registration across multiple carriers.
  • For direct registration with T-Mobile’s analytics provider, use the First Orion Portal. Direct registration often provides faster resolution.
