Spam calls cost twice: robocalls waste your team’s day, and, on the flip side, your own legitimate calls can get labelled “spam likely” on customers’ phones. Cannon VoIP works both sides of that problem.
Blocking the junk before it rings
Keeping YOUR calls off the spam list
The other half of spam protection is outbound. Every Cannon VoIP call carries STIR/SHAKEN attestation, the cryptographic signature receiving carriers use to decide whether your call is trusted, ranked, or flagged. Calls landing at full A-level attestation get the best treatment on the far end.
Don’t take that on faith: ring our free attestation test line at (817) 973-1573 from any line and hear back exactly what your calls carry, attestation level, spam labelling, caller ID as presented versus the name registered to your number. And for the strongest answer-rate play, Branded Calling puts your verified name and logo on the recipient’s screen instead of a bare number.
Inbound spam protection is on by default with Cannon VoIP service, there’s nothing to configure and nothing extra to buy.
