Robocall Mitigation Service

On Monday, March 2, 2020, Allstream launched a robocall mitigation service in the United States to enhance your calling experience with Allstream voice services. The robocall mitigation service is designed to detect and warn Allstream customers of suspected robocall and spam activity using the caller ID name feature on their telephones. This feature is of no cost to you and it will not impact your Allstream services. However, you may have noticed changes in the way caller ID names are displayed on your phones. 

The robocall mitigation service:

  • Identifies suspect calls and alerts customers to possible fraud
  • Continues to display the normal caller ID name on regular calls that are not suspected to be robocall, spam, or fraudulent

How Allstream’s robocall mitigation service works

The robocall mitigation service maintains a fraud score for each identified fraud / spam phone number. Phone numbers identified as having a high probability of conducting fraudulent activity, the caller ID name, which is the name and phone number of the person or business placing a phone call, begin with an appropriate alert and displayed on phones.

You can expect to see new caller ID name information on your phone based on the probability of fraud / spam determined by Allstream’s robocall mitigation service as illustrated below:
