Abstract
The invention relates to a method, a system and a device for controlling sessions between terminals in a network by means of SIP for initiating, maintaining and terminating sessions with the terminals, thereby creating a SIP interdependency between a first and a second terminal. In order to increase the reliability in such networks, the SIP interdependency is created by establishing a first SIP relation between the first terminal and a network element, and a second SIP relation between the second terminal and a network element.
