Abstract

The NATs caused the SIP end-to-end application to become extremely difficult.In this paper we analyzed several kinds of method of NAT traversal for SIP and their pitfalls, proposed a solution SPNT(Shortes Path for NAT Traversal). The basic idea is that the proxy judges the NAT type which the SIP device is behind through the information interacting between the proxy and the SIP device, It takes different methodology to traverse the NAT by the NAT type for the SIP signaling, and the shortest associated media data path between the devices are dynamic established by the connectivity checks to the media addresses. This solution can traverse all NATs in the application layer not changing the existing NAT,and avoids the pitfalls of using any of the other methods alone.
