WebRTC and SIP over WebSocket

Connecting WebRTC compliant devices to the SBC WebRTC Gateway at the edge of the cloud. 2 MUST conditions for solutions are 1. IP device with WebRTC support SIP over WebSocket signalling 2. RTP media transfer, communication protection as they cross network boundaries Embedded device environment: Embedded Linux Libs Available open source libraries can be used Solutions must be efficient, wherever possible 'C' code must be used. Base firmware is in C, but C++ libs can be used Must have prior exprience working on 1. Embedded Linux 2. Must have prior experience successfully completing WebRTC project - reference required. 3. Must have fluency in SIP protocol 4. Positive attitude is a key in solving any challanges in the project Project will not be considered completed only with a successful test on controlled enviroment Field test must be performed in a real-world enviroment for project sign-off 90 days bug fix warranty must be provided Bug fix and new feature will be dealt with separately On-going maintenance will be pay-per-basis hourly rate Experience with embedded firmware development and platforms Solid experience with embedded Linux build systems Significant development experience in C/C++ Experience in developing kernels and device drivers Experience with serial interfaces (UART, SPI, RS485, I2C, etc.) Experience with ZigBee, BLE, Z-Wave and / or WiFi applications Solid understanding of embedded systems and RTOS Experience designing software APIs Experience with Git/BitBucket Timeline: 6-8 weeks.
