INTERCEPTING VOICE OVER IP COMMUNICATIONS AND OTHER DATA COMMUNICATIONS

摘要

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.

主权项

1. A method for causing Internet Protocol (IP) communications to be intercepted in an IP network system in which IP communications between a first party and a second party occur, the method comprising:
receiving from a call controller a request to establish IP communications between the first and second parties; receiving an intercept request message from an entity, the intercept request message including: a) an identification of at least one party whose communications are to be monitored, b) intercept determination information for determining whether communications involving the at least one party are to be monitored, and c) destination information identifying a destination to which copies of intercepted communications involving the at least one party are to be sent; associating with the at least one party, the intercept determination information and the destination information; producing a routing message for receipt by the call controller and separate from any IP communications between the first party and the second party, the routing message providing routing information for routing the IP communications between the first and second party; and when the intercept determination information meets an intercept criterion, causing the routing message to include at least a portion of the intercept determination information and the destination information.
