| 摘 要： | VoIP语音视频流对NAT／Firewall的穿越已经成为语音数据业务开展过程中最大的障碍。Full Proxy提供了一种NAT/Firewall穿越的有效途径。具有很强的适应性和透明性。本文深入讨论了Full Proxy的实现原理和基于Full Proxy的整个呼叫流程，最后在一个嵌入式双CPU系统的基础上实现了一个Full Proxy。

| Abstract: | The traversing of the media and video streams across NAT/FirewaU has been the greatest obstacle in the development of NGN services. Being a practical way of NAT/firewall traversing. Full Proxy shows its expansibliity. In the first place of this paper we analyze the theory of Full Proxy and the call flow based on the full proxy. Then we realize a full proxy on an embedding system with two-cpu. |
