• If a microphone is connected to the sound card: In this case you won’t be able to talk with the other party. Most modems have a half-duplex voice circuit, which means that they can either receive (record) or transmit (play back) digitized voice. You can only talk through internal or external microphone attached to the modem. • If a microphone is connected to the modem: Your modem must support a speakerphone mode, which is intended to provide a full-duplex, hand-free telephone emulation. Usually a speakerphone support is declared on the modem box or in the name of the modem. Press ‘Speak’ button to enter speakerphone mode.
