A method is dedicated to video-conference establishments between audio communication equipments (ACE 1 , ACE 2 ), each associated to a user and to a telephone number and connected to a telephone network (TN), and video communication equipments (VCE 1 , VCE 2 ), each associated to one of these users and to an IP address and each connected to a video equipment (VE 1 , VE 2 ) and to an Internet network (IN). This method consists in a) using a user audio communication equipment (ACE 1 ) to initiate a first call with another user audio communication equipment (ACE 2 ), 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 (ACE 1 , ACE 2 ), 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 (ACE 1 , ACE 2 ), d) determining, if required, the addresses of the user video communication equipments (VCE 1 , VCE 2 ) in order to establish a video communication therebetween, in parallel with the audio communication.
