Method and apparatus for monitoring calls over a session initiation protocol network
First Claim
1. A gateway system for triggering the monitoring of data packets that form a communication in a data packet network, comprising:
- a storage device for storing computer instructions for generating and transmitting data packets having a select header, which select header includes communication monitoring parameters;
a network port for receiving and transmitting the data packets; and
a processor coupled to communicate with the storage device and coupled to the output port wherein the processor generates the data packets with the select header and then transmits them through the network port.

Abstract
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.

9. A method in a gateway device to a data packet network for triggering communication monitoring for a plurality of data packets that form a communication, the method comprising:
-
determining whether a data packet is part of a communication that is to be monitored;
appending a communication monitoring system (CMS) header to the data packet; and
routing the data packet with the appended (CMS) header to a node containing monitoring equipment. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 18, 19, 20)

17. A method for routing data packets in a data packet network, comprising:
-
determining that an original data packet is part of a communication that is to be monitored;
duplicating the original data packet and forwarding one of the original and the duplicated data packets to a node containing monitoring equipment; and
forwarding the other of the original and the duplicated data packets to a specified destination.
