How does the E2EE button behave during a call?

The E2EE button is located within the 'More' section of the active call controls. It allows users to transition a standard call to an 'E2EE call screen' provided the other party also has the necessary RCV permissions.

Does this template cover multi-device or conference call scenarios?

Yes, the template includes specific logic for 'Multi-call' and 'Multi device' scenarios, noting that features like 'Switch over' are disabled during an E2EE call to maintain the secure tunnel.

Can I customize the E2EE settings toggle in Xmind?

Absolutely. You can modify the 'Toggle states' and 'Toggle name' nodes in Xmind to match your specific application's branding or technical requirements while keeping the underlying logic intact.

About

The E2EE phone call mind map template provides a comprehensive technical framework for implementing end-to-end encryption in mobile communication systems. Covering 197 nodes across a detailed logic flow, this E2EE phone call cheat sheet is designed for product managers and security engineers to map out the user journey from activation to error handling. The structure specifically details the 'phone call E2EE settings' logic, including feature flag dependencies like the 'M_USE_E2EE_PHONE_CALL' LD flag and permission requirements for RCV and video. It serves as a robust E2EE phone call template for documenting UI placements, such as the 'Active call page - More' button location, and backend toggle states. By visualizing the transition from standard VoIP to encrypted states, teams can ensure that security protocols do not compromise the user experience during critical 'Call screen' interactions.
