摘　　要：在"Phone to Phone"工作方式的lP电话业务中I,P语音网关起到PS1网和IP网之间的桥梁作用,它转换lP网络和PSTN网的信令,传输语音信息.在分析IP语音网关的基本功能的基础上,提出一种IP电话网关的实现方案以及模块化实现方式,依照SIP协议用C++代码网关功能模块,用MySQL数据库保存用户和呼叫信息,用SNMP协议实现对网关的远程配置与管理.实验表明该网关具有投入少、操作方便、可扩展性强等特点.IP voice gateway play as a bridge linking PSI and IP in IP telephone service of ＂ phone to phone ＂working way by changing IP network and PSTN nets signaling.In the basis of analysis of IP voice gateway,a scheme is raised to achieve IP gateway.According to SIP agreement,C＋＋＋ to achieve gateway remote configuration and management function modules of code gateway,saving the user and call information by the MySQL databases,and SNMP agreement has been used to achieve gateway remote configuration and management.Experiment improves that the gateway has the characteristic of low cost,convenient operation,expandability etc.
