摘　　要：针对SIP用户代理和STUN客户端互通方案的不足,提出了一种新的互通方案。该方案设计了一个SIP用户代理和STUN客户端都可以访问的配置文件作为接口文件,从而使二者成为相互独立的实体。SIP用户代理不需要嵌入STUN客户端,也无需改造其整体架构,仅需读取接口文件的配置信息来完成其系统的初使化,并以文件读取的方式实现SIP用户代理与STUN客户端的互通。最后,以实验验证了新方案的可行性。Aiming at the deficiency of mutual communication between STUN client and SIP user agent, a new scheme is presented. This scheme designs a special configuration file as an interface file, which can be accessed by two isolate entities： STUN client and SIP user agent. It is no necessary for STUN client to be embedded in SIP user agent and the architecture of SIP user agent also does not need to be rebuilt. SIP user agent only realized system initialization by reading the configuration message of the interface file. So it becomes the simple way to achieve mutual communication between STUN client and SIP user agent by reading file. Finally, the feasibility of the new scheme is validated by experiments.
