Development of a WebRTC-Based Secure Voice and Video Messaging Platform with Multi-Device Support

The client currently offers internal text messaging solutions that provide complete control over corporate communications. However, there is a strategic need to extend their services to include reliable voice and video communication that functions seamlessly across multiple devices and network conditions, including 3G networks. Additionally, system reliability, security, and fine-grained permission management are critical to meet client expectations and industry standards.

A mid-sized enterprise specializing in providing private communication solutions for corporate clients, seeking to expand into voice and video communication channels.

• Design and develop a web and mobile compatible voice and video messaging platform supporting peer-to-peer and media server-based communication.
• Ensure high-quality audio and video transmission with consistent performance across various network conditions, including 3G networks.
• Implement end-to-end encryption for all communication traffic to safeguard sensitive corporate data.
• Incorporate advanced permission controls for managing group calls and user roles.
• Enable group call recordings with playback available within 15 minutes post-session.
• Develop a fine-grained permissions system for call coordination and user access management.
• Support multiple device types via dedicated SDKs and HTML5/WebRTC technologies.

• Adaptation for web browsers, iOS, and Android platforms with dedicated SDKs
• Support for secure peer-to-peer (P2P) and media server-based communication via Kurento Media Server
• High-quality audio and video transmission optimized for 3G networks
• End-to-end encryption for all traffic streams
• User permission management systems for call control and group call setups
• Group call recording and playback with minimal delay (available within 15 minutes)
• Fine-grained permission controls for user access and call moderation

• Media streaming servers (Kurento or equivalent)
• Mobile SDKs for iOS and Android devices
• Security modules for encryption and permissions
• Backend authentication and user management systems

• System must support consistent high-quality audio/video streaming across all devices
• Performance tested to maintain reliability on networks with bandwidth as low as 3G
• Group call recordings accessible within 15 minutes of session conclusion
• Strong security measures including end-to-end encryption and permissions control
• Scalable architecture supporting increasing user base

The implementation of a secure, reliable voice and video messaging platform will enhance client engagement by providing seamless communication across devices and networks. Expected benefits include improved user experience, higher system reliability on varied network conditions, and enhanced security. This development aims to increase user adoption, reduce communication barriers, and support the client’s strategic growth into multimedia communication services, similar to the successful outcomes observed in past projects where high-quality streaming and security were achieved over diverse device types and network conditions.
