Offline Campaign
You can tag a phone number that you would like to use for offline campaigns with this option. This will group offline campaigns with your online campaigns for easy access and reporting.
To set up a campaign with this method, select the “Numbers” category from the column on the left side of the online portal.
Scroll down and expand the "Campaign Attribution" section and toggle it on.
The box on the upper right is a drop-down where you select the campaign strategy you would like to use for your toll-free number.
Select "Offline Campaign" from the drop-down.
Be sure to click "Save" when finished.
*It is important to note that when using campaign attribution, all the linked numbers will fall under the "tracking numbers" category instead of the "numbers" category within the user interface.
