The method involves sending a message for verifying availability from a telecommunication terminal (1) to a telecommunication terminal (2) during activation of call bypass functionality at the telecommunication terminal (1). The terminal (2) is identified as bypass destination, and a signaling channel is used for transmission of the message from the terminal (1) to the terminal (2). The signaling channel is verified by the terminal (1) within a pre-selected time period for a reply. |
