In terms of data security CallHippo comes with this feature of number masking.
Number masking helps e-commerce businesses protect customer and business phone numbers. In this feature, numbers in the contacts, call logs, and on the calling screen will be masked i.e.: +918*******9 in this format to prevent any kind of data fraudulent activity.
Hope this was helpful!
