SYSTEM AND METHOD FOR FILTERING SIP-BASED SPAM

摘要

A system for filtering SIP (Session Initiation Protocol)-based spam includes a spam detection unit for receiving a SIP message where labeling is performed from a sending user agent and detecting the spam using a label in the SIP message. Further, the system includes a spam checking unit for checking a call recipient from the SIP message and confirming a spam policy previously set by the call recipient through a spam management server; and a spam filtering unit for filtering the spam based on the confirmed spam policy.
