Dialpad relies on the spam score tied to inbound calls to determine whether or not to allow them to reach an individual user. Inbound calls with a spam score of 100 (the highest possible) are automatically blocked from reaching users in Dialpad.
Reliable third-party sources feed information to Dialpad on each inbound call, declaring the spam score.
If a caller or sender is being sent to spam due to our automatic spam prevention, adding them as a contact will prevent them from being blocked.
