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.

FAQs about call blocking
Call blocking is a feature that you'll find in most business phone systems that will automatically block phone calls from suspect numbers.
It depends. Some apps work by simply blocking all incoming calls from numbers that aren't on your contact list. This can be effective in some cases, but it may also block wanted calls from numbers that you don't have stored in your contacts.
Other apps allow you to manually block specific numbers that you don't want to receive calls from. This can be more effective, but it does require you to take action to block each number individually.
Still other apps use more sophisticated methods, such as analyzing the caller ID information to try and identify spam callers. These can be quite effective, but they may also mistakenly block wanted calls from legitimate businesses or individuals. But these likely won't be free!
There are a few different ways to block calls, depending on your phone and/or service provider.Most phones have a call-blocking feature built in. To use this, you simply add the number you want to block to your list of blocked callers. Once it's on the list, the person calling you from that number will hear a busy signal instead of being able to connect with you.
If you're getting repeated calls from the same number and you can't block them using either of the methods above, you can contact your service provider and ask them to block the number for you. They may be able to do this at no charge, or there may be a small fee involved.
If you want to turn off call blocking, there are a few different ways to do it, depending on the method you used to block calls in the first place.
If you blocked calls by activating the "Do Not Disturb" option in your phone's settings, you can simply go back into the settings and deactivate it.
If you used a call blocker app, you will need to open the app and remove any numbers that you've blacklisted. Finally, if you're using an app that uses more sophisticated methods of identifying and blocking spam calls (like by assigning spam scores), you may need to adjust the settings within the app to allow certain types of calls through.
