External Speakers and Microphone
External speakers and microphones are plug-and-play accessories. You can
connect an external PC-type microphone and powered speakers (with amplifier)
on the Cisco IP Phone by using the line in/out jacks.
Connecting an external microphone disables the internal microphone and
connecting an external speaker disables the internal phone speaker.
Note Using poor quality external audio devices, playing loudspeakers at
very loud volumes, or placing the microphone very close to the loudspeaker may
result in undesirable echo for other parties on your speakerphone calls.
