How to block calls from specific countries

If for whatever reason you don’t want to receive calls from some countries, then you can easily block calls from these places. We will show you how to do it in this step-by-step guide.

Step 1. Go to Tracking > Call Flows. Click on '+ Create' if you want to create a new call flow. To edit an existing one, just click its name to enter the call flow.

Step 2. If you're creating a new call flow, select whether you want to build it from scratch or using our templates. We will go with the template in this example.

Step 3. Select the type of call flow you need by clicking on 'Use template'. We're going with a Simple Call Flow in this guide.

Step 4. Delete the pre-selected 'Dial' filter.

Step 5. Click on the plus '+' sign and select 'Caller ID Prefix' from the filters menu.

Step 6. Fill out the country prefixes of the countries you wish to block all calls from.

Step 7. Click on the plus sign and select to 'Hang up' when you get calls from callers with the ID prefixes you've defined.

Step 8. Finally, click the plus sign once again and select what happens with all other prefixes.

And you're done! No more calls from these places.
