| Abstract: | A DSP-based WMGCP stack running on LAN IP telephony system is implemented in this paper.The WMGCP stack adopts layered structure and session state machine,and accomplishes some functions such as individual calling,group calling,full calling,amplifying calling,storage and parse for WMGCP messages.The WMGCP task is created with μC/OS-II embedded operating system,which shows the good stability and low cost in practice. |
