Abstract: A method for providing dynamic group call among a group of users both wireless (10-30) and wireline (40) places the selectability of the call in the hands of an originating user (10). An originating user (10) may make a fixed number of entries (80). The originating user (10) can create a dynamic group call, add a group call list for later execution, add a member to the group call list, or create a dynamic group call list and immediately execute a group call (92). The method for dynamic group call also provides for selecting a time to live for each group call entry (81) in database (60). This parameter time to live is directly selectable by the originating user (167) or the server. In addition, any member to a previous or existing group call may rejoin or reestablish the dynamic group call (220).
