Abstract
A network node receives a Session Initiation Protocol (SIP) or H.323 signaling packet associated with data traffic, and determines if the data traffic originated from a source node or source network as Voice over Internet Protocol (VoIP) traffic. The network node tags a header of the SIP or H.323 signaling packet with a tag that identifies the data traffic as a VoIP originated call based on the determination, and sends the tagged SIP or H.323 signaling packet towards a destination. The network node further sends data identifying the data traffic as a VoIP originated call to an administrative system for at least one of call billing, rating, settlement or taxation purposes.
