To import a new list of numbers, click on the “Import” button. Your list should be a .csv or .txt file, with “DID”, “TN”, or “phonenumber” in the first row. You can either import a “GLOBAL” list, which will be used for all calling campaigns in your account that are using the “Global Rotation” setting, or choose a specific campaign for your list. Choose the file, then click “Save” to import the list.
To copy a list of numbers from one campaign to another, click on the “Copy” button. Choose the campaign to copy FROM and TO, then click “Copy”.
