ABSTRACT:
A method of establishing video-conferences between audio communication equipments (ACE1,ACE2) comprises a) using a user audio communication equipment (ACE1) to initiate a first call with another user audio communication equipment (ACE2), b) routing the first call to an exchange node (SSPN) of the telephone network (TN) in order it transmits a message, comprising the telephone numbers of the user audio communication equipments (ACE1,ACE2), to a service node (SN) connected to the telephone (TN) and Internet (IN) networks, c) authorizing the exchange node (SSPN) to establish the first call when the telephone numbers are stored in a memory (MY) of the service node (SN), in order to set up an audio communication between the audio communication equipments (ACE1,ACE2), d) determining, if required, the addresses of the user video communication equipments (VCE1,VCE2) in order to establish a video communication therebetween, in parallel with the audio communication.
