Abstract
According to one embodiment, a selectively-expandable speakerphone system allows one or more portable computers to automatically, wirelessly interface with a speakerphone console via an audio access point. A scheduling module initiates the conference call at a scheduled time, whereupon the wireless network interface of each portable computer is automatically switched to an SSID uniquely associated with the audio access point, for connecting to the speakerphone console. The audio signals generated by the laptop microphones are mixed with any audio signal generated by an optional microphone on the speakerphone console, and the mixed audio signals are transmitted over the telephone line. Incoming audio signals are passed to the speakerphone console and wirelessly transmitted to the portable computers for substantially simultaneous playback on the respective loudspeakers.
