First Claim
1. A method of listening in to calls between two or more subscribers of a communications network comprising one or more IP networks, the method comprisingwhen a listening server detects a request to monitor one of the subscribers, said listening server determining at least one call control server associated with the subscriber;
- determining at least one IP router which is responsible for a network access point of the subscriber to the IP network or IP networks;
the listening server causing the at least one determined call control server to acquire call data associated with calls in which the subscriber is involved; and
the at least one determined IP router acquiring contents data associated with calls in which the subscriber is involved.

Abstract
The invention relates to a method of listening in to calls between two or more subscribers of a communications network comprising one or more IP networks as well as to a listening server, a call control server, and an IP router for carrying out the method. When the listening server detects a request to monitor one of the subscribers, it determines at least one call control server assigned to the subscriber. Further, at least one IP router is determined which is responsible for a network access point of the subscriber to the IP network or IP networks. The listening server causes the at least one determined call control server to acquire call data associated with calls in which the subscriber is involved. Further, the at least one determined IP router is caused to acquire contents data associated with calls in which the subscriber is involved.

10. A listening server that supports the listening in to calls between two or more subscribers of a communications network comprising one or more IP networks, wherein the listening server comprises:
-
a control unit; and a database; wherein, when the control unit detects a request to monitor one of the subscribers, the control unit accesses the database to determine at least one call control server associated with the subscriber, and causes the at least one determined call control server to acquire call data associated with calls in which the subscriber is involved. - View Dependent Claims (11)

13. A call control server comprising a control unit that controls calls in an IP network, wherein the call control server further comprises:
-
a listening logic; wherein, when a listening server, in response to a request to monitor a subscriber, has determined the call control server as a call control server associated with the subscriber, said listening server causes said listening logic to acquire contents data associated with calls in which one or more subscribers determined by the listening server are involved. - View Dependent Claims (14, 15)

16. An IP router comprising a control unit that controls the switching of IP packets in an IP network, wherein the IP router comprises:
-
a listening logic; wherein, when a listening server, in response to a request to monitor a subscriber, has determined the IP router as an IP router responsible for a network access point of the subscriber to the IP network, said listening server causes said listening logic to acquire contents data associated with calls in which one or more subscribers determined by the listening server are involved. - View Dependent Claims (17, 18, 19)
