PhoneBurner has the capability to Block / Allow certain area codes during your dial session. With this functionality you can choose only specific area codes to dial or specific area codes to block.
To access this feature follow these steps:
1. Click Call History in the top center
2. Click PhoneBurner® Settings towards the top right
3. Click Limit Area Codes in the middle of the page
By default no area codes are blocked or allowed. At the top of the page you may select Block or Allow from the dropdown, then select any area codes you would like to be included. Be sure to hit Save Changes at the bottom of the page when you are finished.
Note: The list currently only displays US numbers and Toll free numbers. If you are allowed to call Canadian numbers but you need to block some areas you will need to use the Block option. Currently, there is no way to specify any Canadian allowed numbers if you choose the Allow option.
