Leaked screenshots show that Microsoft is working on a new call and SMS blocker, known as ID & Filter, for Windows 10 Mobile . There's no word on when it will be released.

WindowsBlogItalia has posted the leaked screenshots for ID & Filter, which it says will be integrated into Windows 10 Mobile. It will allow users to block calls and messages directly from the user's phone or the Messages app. ID & Filter will also allow users to block calls from different types of businesses, such as real estate agents, taxis, and others.

Besides a new UI users can also add the Microsoft Account to sync the numbers and options across devices.

While there is no release date for ID & Filter, it's possible Microsoft will release it to members of the Insider program in the near future before making it available for all Windows 10 Mobile users.
