Publication number: 20080062978Abstract: The present invention provides an interactive NAT (Network Address Translator) traversal method, i.e. INT (Interactive NAT Traversal) method, for solving the problems of SIP (Session Initiation Protocol) in Internet phone (VoIP) under current Internet environment. In other words, the present invention solves the SIP problems caused by NAT (Network Address Translator) and private (virtual) IP, so that P2P (Peer to Peer) transmission can traverse the NAT firewall directly. The present invention uses the INT method on SIP, forming an interactive NAT traversal method in SIP (SIP with INT, SWINT), to solve the problems that SIP speech packets cannot transmit directly under NAT firewall.Type: ApplicationFiled: November 1, 2006Publication date: March 13, 2008Applicant: Color City Enterprise Co., Ltd.Inventors: Shaw Hwa Hwang, Yao Hsing Chung, Yu Wei Jhang, Chen Hung Wu, Chen Yi Wu, Kuan Lin Chen, Kuo Wei Liu, Chen Yu Yeh
