How does Dialpad's call blocker work?

Automatic call blocking:

Dialpad leverages the spam score tied to inbound calls to determine whether or not to allow them to reach an individual user.

The spam score is maintained by reliable third-party sources that feed that information back to Dialpad on each inbound call. A spam score of 100 (the highest possible) is automatically blocked from entering the Dialpad ecosystem.

Self-serve spam blocking:

In addition to automatically blocking inbound calls with a spam score of 100, Dialpad has self-serve options for blocking calls with a “high spam score” (i.e. any score above 90). Not only that, Dialpad lets you set rules for inbound calls from callers not currently in your contact list, as well as any "anonymous" callers.

These options apply for every inbound call you receive to your direct Dialpad line—we also give you the option to mark new, unsaved numbers as spam for one-off calls that you may receive.

Say goodbye to spam

Dialpad offers a number of different ways to stop spam calls in their tracks. Here are just a few options:

  • Full block (play “Number not in service” message)

  • Straight to voicemail (no notification)

  • Straight to voicemail (notification plus real-time transcription)

  • IVR screening (“Please state your name and Dialpad will try to connect you”)

Regardless of what you choose, all your spam calls will automatically filter into a Spam tab in your Dialpad inbox for you to review later—whether that’s simply checking the caller or reading through the voicemail transcription.
