Abstract
A customized list of real-time conference participants are obtained by selecting one or more logical operators such as AND or OR and applying the one or more logical operators to conference groups the user has selected. The logical operators and selected conference groups are sent to a conference server, which applies the operator to the selected groups to arrive at a shortlist of conference participants. The invention is particularly useful for cellular telephones initiating a real-time conference using the Session Initiation Protocol (SIP) and a SIP server resident on a network.
