1.2 Using YourSpeakerphone
When using your speakerphone, the microphone and loudspeaker are
farther awayfrom you than when you use a handset. Both the signal from
the loudspeaker and the signal to the microphone must be strengthened.
When microphones and loudspeakersare close together (such as in a
speakerphone),additional amplification typically generates a ringing
sound (public address systems do this if the volume is too high or the
microphone is too close to a loudspeaker).

half-duplexm ode.Both sets of guidelines (section 1.2.1 and
