Security +- Encryption Strength: Ensure that the encryption algorithms used (e.g. + AES-256, RSA, ECC) are up-to-date and secure. +- Key Management: Evaluate the mechanism for generating, distributing, and + storing encryption keys (e.g., public-key cryptography, Diffie-Hellman, or + ECDH). +- Forward Secrecy: Confirm that the protocol supports forward secrecy, meaning + that session keys are discarded after use to prevent future decryption of + past communication. +- End-to-End Encryption Integrity: Verify that no plaintext data is exposed + outside the encryption boundary (client-side only). +- Zero Knowledge: The protocol and library should implement zero-knowledge + principles, ensuring that the server cannot access or decrypt the + communications. +- Authentication and Authorization: Evaluate the authentication method (e.g., + multi-factor authentication) and ensure that only authorized users can + initiate calls. +- Replay Protection: Ensure that mechanisms are in place to prevent replay + attacks (e.g., using nonces or timestamps). + +2. Performance +- Latency: Measure the round-trip time (RTT) for call setup and audio quality + during the call. A good system should aim for low latency to ensure real-time + communication. +- Bandwidth Efficiency: Evaluate the protocol’s ability to minimize bandwidth + usage while maintaining acceptable audio quality. +- Scalability: Ensure that the protocol can handle varying user numbers and + call volumes without degradation in performance. +- Audio Quality (Codec Selection): Assess the choice of audio codecs (e.g., + Opus, G.711) for their impact on call quality at different network + conditions. + +3. Usability +- Ease of Integration: Evaluate how easy it is to integrate the library into an + Android application, including the availability of well-documented APIs and + clear examples. +- Cross-platform Compatibility: Ensure that the protocol supports multiple + platforms (e.g., Android, iOS, desktop) to allow seamless communication + between devices. +- Seamless User Experience: Check for smooth call initiation, handling of + dropped calls, and reconnection strategies. The app should handle background + operation gracefully. +- UI/UX Design: Assess the user interface (UI) of the Android dialer for + intuitiveness, accessibility, and design consistency. +- Error Handling and Recovery: Evaluate how the system handles unexpected + errors (e.g., network issues, connection drops) and recovers from them. + +4. Interoperability +- Support for Multiple Protocols: Verify if the library and protocol can + integrate with existing standards (e.g., SIP, WebRTC) for interoperability + with other services. +- Cross-device Compatibility: Ensure that calls can be initiated and received + across different devices, operating systems, and network conditions. +- Backward Compatibility: Test whether the library is backward compatible with + older versions of protocols or legacy systems where applicable. + +5. Privacy +- Data Storage: Evaluate how the system stores any data (e.g., user details, + call logs). Ensure that sensitive information is encrypted both in transit + and at rest. +- Data Minimization: Ensure that only the minimum necessary data is collected + for the protocol to function. +- No Call Metadata Storage: Ensure that no metadata (e.g., call logs, duration, + timestamps) is stored unless necessary, and, if stored, it should be + encrypted. + +6. Compliance and Standards +- Regulatory Compliance: Ensure that the protocol adheres to privacy and + security regulations, such as GDPR, HIPAA (if relevant), and other + region-specific laws. +- Open Standards: Verify whether the protocol adheres to recognized open + standards for secure voice communications (e.g., ZRTP, DTLS). + +7. Reliability +- Connection Stability: Test the stability of the connection during real-world + use cases (e.g., fluctuating network conditions, roaming, mobile data). +- Error Logging and Monitoring: Assess the logging system to track errors, + anomalies, or potential security threats. The system should have proper + monitoring to help with diagnosing issues. +- Redundancy and Failover: Ensure that the system can handle server failures or + network issues gracefully with proper redundancy mechanisms in place. + +8. Maintainability +- Code Quality: Review the library for clarity, readability, and + maintainability of the code. It should be modular and well-documented. +- Documentation: Ensure that the protocol and library come with thorough + documentation, including how-to guides, API references, and troubleshooting + resources. +- Active Development and Community: Check the active development of the + protocol and library (e.g., open-source contributions, GitHub repository + activity). + +### Dialer +1. User Interface +- Design and Layout: Ensure that the dialer interface is simple, intuitive, and + easy to navigate. Buttons should be appropriately sized, and layout should + prioritize accessibility. +- Dialer Search and History: Ensure there’s an efficient contact search, + history logging, and favorites integration. +- Visual Feedback: Verify that the app provides visual feedback for actions + such as dialling, incoming calls, and call termination. + +2. Call Management +- Call Initiation: Test the ease of initiating a call from contacts, recent + call logs, or direct number input. +- Incoming Call Handling: Verify the visual and audio prompts when receiving + calls, including notifications for missed calls. +- Call Hold/Transfer/Forward: Ensure the dialer supports call hold, transfer, + and forwarding features. +- Audio Controls: Check whether the app allows users to adjust speaker volume, + mute, and switch between earpiece/speakerphone. +- Call Waiting: Verify that call waiting functionality works, allowing users to + switch between active calls. +- Call Recording: If supported, check whether the call recording feature works + in compliance with privacy regulations and user consent. + +3. Integration with System Features +- Permissions: Ensure the app requests and manages necessary permissions (e.g., + microphone, camera for video calls). +- Integration with Contacts: Ensure that the app seamlessly integrates with the + Android contacts and syncs correctly with the address book. +- Bluetooth Support: Test whether the app supports Bluetooth devices such as + headsets and car kits. +- Notifications: Ensure that call notifications work even when the app is in + the background or the phone is locked. + +4. Battery and Resource Management +- Battery Usage: Evaluate the dialer app’s impact on battery life during active + calls and idle periods. +- Resource Efficiency: Ensure the app doesn’t excessively consume CPU or memory + while operating, especially during idle times. + +5. Security and Privacy +- App Encryption: Ensure that any stored data (e.g., contacts, call logs) is + encrypted. +- Secure Call Handling: Verify that calls are handled securely through the + encrypted voice protocol. +- Minimal Permissions: The app should ask for the least amount of permissions + necessary to function (e.g., no unnecessary location or contacts access). + +6. Reliability +- Crash Resistance: Test for the app’s stability, ensuring it doesn't crash or + freeze during use. +- Network Resilience: Test how the dialer handles varying network conditions + (e.g., switching between Wi-Fi and mobile data). +- Reconnect and Retry Mechanisms: Ensure that the dialer can gracefully handle + dropped calls and reconnect automatically.
