Explaining spam likely flags and what to do in case your number has been flagged.
US Carrier Call Flagging and Blocking
Simplifi has become aware that major carriers in the US industry are actively flagging and sometimes blocking calls to their subscriber's devices due to them deeming the calls as potentially fraudulent. End users may see "Fraud Risk", "Spam Risk", "Potential Spam", "Robocaller", "Scam Likely" and other names which their carriers are prepending onto your caller IDs. Some calls will reach a busy tone.
What to do
We understand that there are many valid & legitimate use cases, where there is a necessity for high-volume calls (e.g. alerts, appointment reminders, etc.) Providers and their analytics partners have established mechanisms for callers to seek redress to fix any inadvertent call labeling or blocking concerns, as well as to register their numbers in the first instance.
The first step is to register with the Free Caller Registry. Several carriers use that to pull company information for phone numbers so having your numbers registered here will help lower the chances of terminating carriers flagging your numbers for spam.
