A method and system for group communications between a plurality of endpoints (102, 106, 108 etc.) in a system (100) is described. The method includes the steps of: a) receiving at a group entity (104) from an initiating endpoint (102), using a transactional protocol, a first message requesting a session between a plurality of endpoints (106, 108 etc.) affiliated with a group that correlates to the group entity (104); b) causing the session to be accepted; c) causing the presence of the session to be communicated, using a broadcast protocol, to the plurality of endpoints (106, 108 etc.) affiliated with the group; and d) communicating from the group entity (104) to the initiating endpoint (102), using the transactional protocol, the acceptance of the session.
