More and more businesses are facing a major issue: their professional phone numbers are being marked as "Spam" or "Suspect" on their customers' devices. This can seriously damage your reputation and reduce the response rate to your calls. Fortunately, there are solutions to whitelist your number and avoid these blocks.
Why Is Your Number Considered Spam?
Carriers and call filtering apps use several criteria to determine if a number is suspicious:
- A high volume of calls made in a short period.
- User complaints or reports.
- Previous use of the number by spammers.
- Lack of authentication compliant with STIR/SHAKEN standards.
