Abstract: The invention relates to a method, party challenging device (18) and computer program products for providing a challenge to a first terminal (10) intending to communicate with a second terminal (24) via two networks (N1, N2). The party challenging device receives a first electronic message (1M) concerning a transfer of media from the first terminal to the second terminal sent from the first terminal (10) and addressed to the second terminal (24), obtains communication contextual data associated with the first party or the first terminal, provides an electronic challenge message (CHM) including a challenge (CHl1) based on the obtained data and sends the challenge message to the first terminal in order to enable a decision to be made how to process the invitation message for the second terminal based on the correctness of a response (RM) including a response to the challenge.

Abstract: The present invention relates to methods and devices for detecting persistency of a first network node (12). In a first aspect of the invention, a method is provided comprising the steps of monitoring (S101), during a specified observation period, whether the first network node has established a connection to a second network node (13), and determining (S102) a total number of sessions of connectivity occurring during said specified observation period in which the first network node connects to the second network node. Further, the method comprises the steps of determining (S103), from the total number of sessions, a number of sessions comprising at least one communication flow between the first network node and the second network node, and determining (S104) inter-session persistence of the first network node on the basis of the total number of sessions and the number of sessions comprising at least one communication flow.
