TAGGING VoIP ORIGINATED TRAFFIC

A network node, comprising:

• a communication interface;
• and
• a processing unit configured to:
• receive, via the communication interface, a Session Initiation Protocol (SIP) or H.323 signaling packet associated with data traffic,
• determine if the data traffic was sent from a source node or source network as Voice over Internet Protocol (VoIP) traffic,
• modify 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
• send, via the communication interface, the tagged SIP or H.323 signaling packet towards a destination.

A method, comprising:

• receiving a Session Initiation Protocol (SIP) or H.323 signaling packet associated with data traffic;
• inspecting a header of the SIP or H.323 signaling packet to identify a tag in the header that indicates whether the data traffic originated from a source node or source network as Voice over Internet Protocol (VoIP) traffic;
• and
• routing the data traffic based on whether the tag in the header indicates that the data traffic originated as VoIP traffic.
