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.
Using poor quality external audio devices, playing loudspeakers at very loud volumes, or placing the
Note
microphone very close to the loudspeaker may result in undesirable echo for other parties on your
speakerphone calls.
Headsets
Cisco Systems performs internal testing of third-party headsets for use with Cisco IP Phones. But Cisco does
not certify or support products from headset or handset vendors.
Headsets connect to your phone using either the USB or the auxiliary port. Depending upon your model of
headset, you have to adjust your phone's audio settings for the best audio experience, including the headset
sidetone setting.
After you apply a new sidetone setting, wait one minute and then reboot the phone for the setting to be stored
in flash.
The phone reduces some background noise that a headset microphone detects. You can use a noise canceling
headset to further reduce the background noise and improve the overall audio quality.
Cisco recommend the use of good quality external devices; for example, headsets that are screened against
unwanted radio frequency (RF) and audio frequency (AF) signals. Depending on the quality of headsets and
their proximity to other devices, such as mobile (cell) phones and two-way radios, some audio noise or echo
may still occur. Either the remote party or both the remote party and the Cisco IP Phone user may hear an
audible hum or buzz. A range of outside sources can cause humming or buzzing sounds; for example, electric
lights, electric motors, or large PC monitors.
