1. A method of monitoring an Internet Protocol (IP) call in a network comprising:
- detecting when a first communication device initiates the IP call with a second communication device;
determining if the IP call is to be monitored;
locating an IP address of a third communication device and an identifier associated with one of the first communication device or the second communication device; and
sending at least one data packet including an alert signal to an IP gateway serving the third communication device based on said locating step, said at least one data packet being associated with the IP call.

Abstract
Surveillance of IP telephony may be performed through the use of conventional telephone equipment, according to principles of the invention while preventing giving indication to the monitored phone by alerting the user of the monitoring phone to such surveillance use prior to pick up by an agent for engagement of the monitoring phone in response to the alert. Such alerts may assume many forms such as ringing, visual indicators, data readouts, activating ancillary equipment, various flags, etc. This alert prior to surveillance is distinct from alerts used for normal non-surveillance calls, which the monitoring phone is capable of receiving.

12. A method of monitoring an Internet Protocol (IP) call in a network comprising:
-
storing a list of communication devices, said list comprising communication devices under surveillance; detecting when an IP call is initiated by a call-initiating communication device to a target communication device in the network; determining if the target communication device is on said list; locating an IP address of a monitoring communication device; receiving an alert signal at the IP gateway serving the monitoring communication device; and sending, via a gateway annunciation, the alert signal to the monitoring communication device based on said locating step, wherein the alert signal indicates an existence of the IP call and a monitoring purpose to be performed. - View Dependent Claims (13, 14, 15, 16, 17)

18. An apparatus for monitoring an Internet Protocol (IP) call in a network comprising:
-
a storage device for storing a list of identifiers associated with communication devices to be monitored; a Watchdog processor for detecting when an IP call is initiated by a call-initiating communication device to a target communication device in the network and for determining if the IP call is to be monitored; an IP gateway for receiving an alert signal, based on an IP address location of a monitoring communication device, wherein the IP gateway is associated with the monitoring communications device; and an annunciator for sending an alert signal responsive to said Watchdog processor to the monitoring communication device, wherein the alert signal indicates an existence of the IP call and a monitoring purpose to be performed. - View Dependent Claims (19, 20, 21, 22, 23)
