This could be caused by the carrier used by the receiver's end that has marked the number as Spam. The DID is probably being spoofed by spammers/scammers which causes the providers to see the DID as SPAM. Unfortunately, there is no way to identify spoofed numbers because they use the same paths and look the same as any other legitimate phone call. You can report these calls to the FCC for further investigation. Below are some helpful links on Spoofing:
If you are instead suspecting calls that are coming from spoofed numbers see our FAQ article - How do I handle calls from suspected spoofed DIDs?
Calls Labeled as Potential SPAM or Being Blocked?
Multiple companies provide analytics, each with their own tracking and radar systems. It is possible your numbers are being blocked or labeled as SPAM due to false flagging.
