Abstract
Apparatus and method to transmit a speakerphone active indication signal to another party over a telephone line upon use of a speakerphone feature, and to transmit a speakerphone inactive indication signal upon cessation of the speakerphone feature. A speakerphone indication transmit module provides an audible or data signal relating to the activation or inactivation of a speakerphone feature to a receiving party's telephone system, which either audibly confirms use of the speakerphone at the opposite end, and/or displays a speakerphone active indication, e.g., on an LED or LCD display. The speakerphone indication active and inactive signals can be, e.g., a single tone, a DTMF tone, FSK signaling, or ADSL signaling.
