发明名称 Method and apparatus for monitoring calls over a session initiation protocol network
摘要 An apparatus and method are formed to add a header to a data packet being transmitted into a data packet network for a communication that is to be monitored. The header causes the data packet to be routed to a specified system node that contains monitoring equipment. The specified system node then forwards the data packet to an exit node. The header is stripped prior to exiting the data packet network to a destination system or device so that there will be no indication that the call was monitored. In an alternate embodiment, a duplicate packet is created wherein one packet is routed to a specified destination for the communication while the other data packet is routed to a node containing monitoring equipment.
