Even customers with legitimate voice business sometimes report that their outbound calls get marked as "Scam likely" or other labels that result in calls not being answered and even blocked.
One way to reduce this risk is to register your number with each of the carriers or their call analytics providers. By doing so, you will let them know you and your business are legitimate and that your customers are expecting your calls.
Registering your number will solve "mislabeling" but it is not a guaranteed whitelist. Registered numbers can still be flagged again if certain call patterns are detected inconsistent with registered usage OR if your contacts file spam and fraud reports against your number. Possible reasons on why your phone number are flagged:
The calling number has a low answer rate from end users
The calling number generates low-duration calls
The calling number is responsible for large volumes of unwanted calls
