Suspected Spam caller when using AWS Connect

Phone numbers can get on these list for various reasons which potentially is not in direct control of the Customer of AWS. I'd recommend to open an AWS Support Ticket and may check the CNAM section on the Administrator Guide (even it's for the US).

You can also setup an alternative number in Amazon Connect to be shown on outbound numbers to overcome that issue.

Hi there,

As part of changes within the US Public Telephone network and a move to alternative reputation mechanisms, as of March 31, 2023, Amazon Connect no longer sets CNAM configurations.

We conducted research between January and March 2023, that showed CNAM was seen by fewer than 7% of users. This is due to changes within support for mobile providers and due to the migration to app-based reputation mechanisms.

All existing CNAM configurations set up before March 2023, are still in place. We will continue to focus on supporting modern replacement mechanisms added to our marketplace, for example, First Orion and Neustar.
