摘要
Disclosed are an interworking system between IP networks using different IP addressing scheme, an application layer gateway (ALG), a network address translator, an interworking method, and a SIP message routing method. The interworking system between a local network using a private IP and a global network using a global IP includes a STUN server and an application layer gateway (ALG). The STUN server provides binding information of header information of a global IP binding request. The application layer gateway (ALG) performs a global IP binding request with header Information changed by IP masquerading, and performs routing by applying the received binding information to media receiving address information of a SIP message.
