Abstract

Method and apparatus for providing a call-tapping point (13) in a switched network with point-to-multipoint functionality. The tapping point is added as an additional destination for data being sent from a source node (11) to a first destination node (12). The tapping point is also added as a destination for data being sent from the first destination node to the source node. A merge operation is performed for finding and combining common segments of the paths between the source and destination, the source and tapping point, and the destination and tapping point.
