【摘要】 在一套VoIP(IP电话)开发系统上,简化控制信令转换的MGCP(媒体网关控制)协议使基于局域网的信令传输和交换过程简单,减少了连接延迟时间,并可降低出错率;并使用软件状态机的方法,使得协议的实现结构简单,易于调试。此简化系统方案可应用于简单的局域网内,没有真正的呼叫中心,但是可以根据不同需求,在每个网关中增加类似呼叫中心的各种增值服务。更多还原

【Abstract】 In VoIP development system,a simplified MGCP protocol makes signals processing and communicating easy,and delay time and faultprobability are reduced.Software state machine is used in application,which makes program’s architecture easyand debug easily.This system design is applied in simple local area network,which has no call center.But special service such as call center could be added according to actual requirements.更多还原
