Abstract

A method and corresponding equipment for setting up a conference call via a communication network that uses session initiation protocol (SIP) signalling for call setup, the method including steps (Ela E2a E3a E4a) of providing during the call setup signalling to a subscriber invited to participate in the conference call an indication that the call is a conference call and including in the call setup signalling a reference to a group document indicating information about the conference call, such as the other invited participants, or including the group document itself.
