After years developing a software SIP client, Saúl wondered how will it be to develop a hardware one. Using platforms such us Raspberry Pi, it's possible to work on low cost hardware projects reusing GNU/Linux knowledge, so Saúl got on with it. The result is OP2: an SDK which acts as a firmware for SIP hardware devices, and more!
Saúl discovered VoIP in 2005 and has been learning and recommending the use of SIP protocol since then. Pythonist to the death and open software enthusiast, invests 95% of his time in projects under open licenses.
