Intercepting voice over IP communications and other data communications
Methods and apparatus for intercepting communications in an Internet Protocol (IP) network involve maintaining dialing profiles for respective subscribers to the IP network, each dialing profile including a username associated with the corresponding subscriber, and associating intercept information with the dialing profile of a subscriber whose communications are to be monitored. Intercept information will include determination information for determining whether to intercept a communication involving the subscriber, and destination information identifying a device to which intercepted communications involving the subscriber are to be sent. When the determination information meets intercept criteria communications are established with a media relay through which communications involving the subscriber will be conducted or are being conducted to cause the media relay to send a copy of the communications involving the subscriber to a mediation device specified by the destination information.
1. A method for intercepting communications in an Internet Protocol (IP) network system in which communications between a subscriber of the system and another party occur through a media relay to which the subscriber and the another party address their communications destined for each other and which relays the communications between the subscriber and the another party, the method comprising:
determining whether determination information associated with a subscriber dialing profile associated with the subscriber meets intercept criteria;
producing a routing message for routing communications involving the subscriber through components of the IP network, after determining whether the determination information meets the intercept criteria, the routing message being separate from any message sent between the subscriber and the another party;
when the determination information meets the intercept criteria:
including at least some of the determination information and destination information associated with the subscriber dialing profile in the routing message; and
in response to the routing message, causing the same media relay through which communications between the subscriber and the another party are relayed to produce a copy of the communications between the subscriber and the another party, while the same media relay relays communications between the subscriber and the another party; and
in response to the routing message, causing the same media relay to send the copy to a mediation device identified by destination information.

12. The method of claim 11 , further comprising maintaining direct-in-dial (DID) records associating Public Switched Telephone Network (PSTN) telephone numbers with usernames of users subscribing to the IP network, and wherein finding a dialing profile associated with the subscriber whose communications are to be monitored comprises finding a username in a DID record bearing a PSTN number associated with the subscriber whose communications are to be monitored and using the username to locate a dialing profile associated with the username.
13. The method of claim 3 , wherein associating the determination information and the destination information comprises populating intercept information fields in the dialing profile of a subscriber whose communications are to be monitored.
14. An apparatus for intercepting communications in an Internet Protocol (IP) network, the apparatus comprising:
