Abstract
The invention relates to a method and a system for IP-based telephony and video conferencing between at least one IP node (10) and a second terminal (30/31). According to said method, authentication data is transmitted from an identification module (11) of the IP nodes (10) and registration data is transmitted to a registration module (51). The IP node (10) is authenticated using an authentication module (20) and a home location registry (25). Corresponding location data is stored in the location database and is forwarded to the identification module (11) of the IP node (10). Said IP node (10) is then released for IP based telephony or video telephony.
