The present invention relates to a method for monitoring media flow in a telecommunication network. The network comprises a media-handling node (MHN) through which, sessions between subscribers are transported via first ports (PI1-PI5) and second ports (PO1-PO5). An extra port (XP1-XP5) is assigned to the media-handling node (MHN) for each new session that is transported through the node. The method comprises the following steps: storing in a database (LI-DB), identification of a first subscriber (A) for which monitoring is desired; a connection is set-up between the first subscriber (A) and second subscriber (B); an assigned extra port (XP1) that is adherent to the session between the first and second subscriber (A, B) is connected; the session between the first and second subscriber is monitored via the connected extra port (XP1).
