Abstract:
The present invention relates to a method and system of detecting anomaly traffic for VoIP applications, in which a router captures an IP packet of a VoIP flow being transmitted, the captured IP packet is classified into an SIP message and a RTP traffic, header information is extracted from the classified SIP message and RTP traffic, the extracted header information is stored in a database, and whether SIP-based anomaly traffic or RTP-based anomaly traffic is generated is determined based on the extracted and stored information, and to a system therefor.
