Abstract
Processing Session Initiation Protocol (SIP) signaling in a voice/data integrated switching system includes: transceiving a message and data between a terminal and a system using a Voice over Internet Protocol (VoIP) SIP 'INFO' method upon communication being performed between terminals via an Internet Protocol (IP)network and using a VoIP SIP 'MESSAGE' method in an idle state upon communication not being performed between the terminals; processing proprietary signaling of a legacy voice switching system as standard signaling using standard VoIP SIP signaling, and simultaneously and separately processing the standard SIP signaling and the proprietary signaling of the legacy voice switching system in a system using the VoIP SIP signaling.
