In Adversus you have the possibility to clean up your invalid numbers. This validates if there are any valid numbers defined for the campaign lead, and delete those which do not have a valid number. The numbers are checked according to the regional number plans, and against the numbers that have been blacklisted.
To make a clean of invalid numbers do the following:
1. Go "Warehouse" and afterwards "Leads"
2. If you only want to make the clean up on specific campaigns for an example, you can filter based on the campaign:
3. When you have created the potential filter you go to "Actions" and afterwards "Clean up invalid leads":
4. Afterwards you choose "Remove invalid leads".
