Understanding call masking

Call Masking hides a pre-determined number of digits of the called, calling number, and/or the service number, as displayed in the Spend Analysis and Services modules, as well as any data exports from the modules or reports:

• The called number is either masked or unmasked, depending on how the customer has instructed the carrier to implement this. This may range from masking all called numbers or it can be selective to specific customer telephone numbers. The customer can also request via their Vodafone partner or operating company to mask called numbers at company level or individual customer telephone numbers (VIP).
• The calling number is masked by default.
• The service number is not masked by default, but you can mask individual service numbers or all service numbers belonging to an account.

You may want to unmask the service number. The CTN Masking setting in the Accounts or Services modules will allow you to do this. This masking protects the identity of the service owner during data analysis. However, note that even if your service number is configured for masking and will appear masked in reports, you will always be allowed to see your own service number.

Masked service numbers appear with asterisks replacing the last 4 digits as follows:

Administrators can configure call masking of the CTN at the Account level and the Service Number level. To learn how to configure call masking, see Configure call masking for a service.

Account level masking applies to all services that belong to that account; however, an individual service number's masking takes precedence over the account setting, unless the account setting is stricter. See the following table for details:
