摘　　要：基于DSP技术设计实现了一种运行于局域网VoIP电话通信系统的WMGCP协议栈。采用分层结构和会话状态机设计,完成基本呼叫、群呼、全呼和扩音呼叫功能,实现WMGCP消息的构建、存储和解析,利用μC/OS-Ⅱ嵌入式实时操作系统创建WMGCP任务。实验表明该协议栈运行稳定,节省了系统资源和成本。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 ca/ling, 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.
