Abstract
A telephone interface ( ) that supports a first and a second conference call service is provided in a telephone-capable apparatus ( ). An input device ( ) is further provided, allowing a conference call conferee to provide participation status data to a controller ( ) of the apparatus. The controller provides a message to a switch ( ), responsive to the participation status data, instructing the switch to provide the apparatus with communication resources commensurate with the participation status data. When the participation status data indicates that the conferee is a speaking and listening conferee, the message instructs the switch to provide resources sufficient to support the first conference call service and a send-only version of the second conference call service. When the participation status data indicates that the conferee is a listening-only conferee, the message instructs the switch to provide resources sufficient to support a receive-only version of the second conference call service.
