Abstract
A service node in a telecommunication network is arranged to receive a Multi-Media video call setup for a terminal to be called. The called terminal is called by the service node according to either a video or a voice call setup, depending on a current allowed answer mode of the called terminal. Responding to the call setup will, depending on either answering or rejecting the call setup by the called terminal, and depending whether the call setup is for a voice or a video call, be handled by the service node according to a predetermined method. When a call setup is answered by the called terminal, the service node further supports a method of toggling between a video call and a voice call at the called terminal.
