| Abstract: | The design of high performance-cost radio ethernet SIP phone with STUN support is introduced.The design uses SDA80D51 as the MCU and DSP unit and RTL8019AS as the network interface.In consideration of the limited resources of embedded system,a SIP stack structure and STUN realization arithmetic fit for embedded system are designed and realized.Some skills and methods optimized the code and data storage are also given. |
