Call Blocking & Spam Prevention

Dialpad uses both an automatic spam blocking system, which applies to any call entering the platform, and user-level settings that provide more granular control over how calls to your Dialpad number are handled.

Let's take a look at call blocking and spam prevention in Dialpad.

Automatic Spam Blocking

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 back to Dialpad on each inbound call, declaring the spam score.

Custom Spam Blocking

Users can also control what occurs when a 'spammy' call reached their Dialpad account. Decide which types of callers are considered spam and how they're handled.


From, navigate to Your Settings Call Handling & VoicemailCall Blocking & Spam Prevention.

Choose whether or not to prevent calls from anonymous callers, callers already not in your Contacts list, and callers with a high spam score.

If you opt-in to prevent any of these calls, you'll see these options for call handling:

  • Send to voicemail and directly to spam folder — no notification
    • Calls will not ring your devices; missed calls and voicemails will be sent to the spam folder in your inbox automatically
  • Send to voicemail, but show me a real-time transcription
    • Calls will not ring your devices; if the caller leaves a voicemail, you'll see the transcript of the message to decide if the caller is important or not
  • Play caller's name when I pick up (does not apply to callers already in your address book; callers will be asked to state their name in order to be connected
    • Callers hear an IVR that says 'Hello, please state your name after the tone and Dialpad will try to connect your call' before ringing your devices
    • Upon picking up, you'll hear 'Hello, [name] is trying to reach you via Dialpad; press 1 to accept this call'

Any changes will immediately take effect in the Dialpad app.

View Spam Calls


From the Dialpad app, navigate to InboxSpam.

You'll see a list of calls marked as spam. If the caller left a voicemail, you can listen to it or read the transcript.

If you'd like to unmark a call from a known contact or number because it is not spam, open the drop-down alongside the call and select Not Spam.

Manage Blocked Contacts & Numbers


From the Dialpad app, navigate to ContactsBlocked.

You'll see a list of any contacts and numbers that are blocked. Choose one, and you'll see Unblock as an option in a banner at the top of the conversation thread.
