In communication system ( 200 ), a packet data terminal ( 102 ) (e.g., personal computer (PC), personal digital assistant (PDA), telephone, mobile radiotelephone, network access device, Internet peripheral, and the like) initiates, coordinates, and controls the provision of on-demand conference call and call waiting services as a function of user inputs without the need for coordination of network resources that dominate conference call service as currently known and practiced. The packet data terminal permits users to establish call conference services for originating and terminating calls, alike. In addition, multi-party call waiting (two or more parties on-hold) services are established.
