FIELD: technology for providing real time communication between a phone and Internet network users.
SUBSTANCE: the method for setting up communication line between first terminal having dedicated routed address, working in first network, and second terminal, working in second network, wherein each terminal is identified by means of an alias address, to which one of the set of routed addresses may be assigned, includes the following: the request for setting up a connection from first terminal includes address of function for ensuring inter-network interaction, through which calls are routed from first network for second network, connection setup request is routed to function for ensuring inter-network interaction, first terminal also communicates the alias address for second network terminal to the function for ensuring inter-network interaction, the routed address, assigned to alias address, is determined through function for ensuring inter-network interaction, and communication line is set up between first and second terminals through routed address.
EFFECT: the mobile terminal does not "dial" the address of electronic mail client, but instead requests a setup of common phone call (voice or video) with the function for ensuring inter-network interaction (IWF).
