You can use the headset with all of the features on the Cisco Unified IP Phone,
including the Volume and Mute buttons. Use these buttons to adjust the ear piece
volume and to mute the speech path from the headset microphone.
Disabling a Headset
You can disable the headset through the Cisco Unified Communications Manager
Administration application. If you do so, you also will disable the speakerphone.
To disable the headset from Cisco Unified Communications Manager
Administration, choose
Device > Phone
and locate the phone that you want to
modify. In the Phone Configuration web page for the phone, check the
Disable
Speakerphone and Headset
check box.
Using External Devices with Your Cisco Unified IP Phone
The following information applies when you use external devices with the
Cisco Unified IP Phone:
Cisco recommends the use of good quality external devices that are shielded
(screened) against unwanted radio frequency (RF) and audio frequency (AF)
signals.
Depending on the quality of these devices and their proximity to other devices
such as mobile phones or two-way radios, some audio noise may still occur. In
these cases, Cisco recommends that you take one or more of the following actions:
•
Move the external device away from the source of the RF or AF signals.
•
Route the external device cables away from the source of the RF or AF
signals.
•
Use shielded cables for the external device, or use cables with a better shield
and connector.
•
Shorten the length of the external device cable.
•
Apply ferrites or other such devices on the cables for the external device.
Cisco cannot guarantee the performance of the system because Cisco has no
control over the quality of external devices, cables, and connectors. The system
will perform adequately when suitable devices are attached using good quality
cables and connectors.
